Detailed Description

Implementation of SBML's UnitDefinition construct.

Units of measurement may be supplied in a number of contexts in an SBML model. The SBML unit definition facility uses two classes of objects, UnitDefinition and Unit. The approach to defining units in SBML is compositional; for example, meter second –2 is constructed by combining a Unit object representing meter with another Unit object representing second –2. The combination is wrapped inside a UnitDefinition, which provides for assigning an identifier and optional name to the combination. The identifier can then be referenced from elsewhere in a model. Thus, the UnitDefinition class is the container, and Unit instances are placed inside UnitDefinition instances.

Two points are worth discussing in the context of SBML units. First, unit declarations in SBML models are optional. The consequence of this is that a model must be numerically self-consistent independently of unit declarations, for the benefit of software tools that cannot interpret or manipulate units. Unit declarations in SBML are thus more akin to a type of annotation; they can indicate intentions, and can be used by model readers for checking the consistency of the model, labeling simulation output, etc., but any transformations of values implied by different units must be incorporated explicitly into a model.

Second, the vast majority of situations that require new SBML unit definitions involve simple multiplicative combinations of base units and factors. An example is moles per litre per second. What distinguishes these sorts of unit definitions from more complex ones is that they may be expressed without the use of an additive offset from a zero point. The use of offsets complicates all unit definition systems, yet in the domain of SBML, the real-life cases requiring offsets are few (and in fact, to the best of our knowledge, only involve temperature). Consequently, the SBML unit system has been consciously designed to simplify implementation of unit support for the most common cases in systems biology. The cost of this simplification is to require units with offsets to be handled explicitly by the modeler.

Summary of the UnitDefinition construct

UnitDefinition has two attributes and one subelement. The two attributes are 'id' and 'name', and the subelement is ListOfUnits.

The required attribute 'id' and optional attribute 'name' are both strings. The 'id' attribute is used to give the defined unit a unique identifier by which other parts of an SBML model definition can refer to it. The 'name' attribute is intended to be used for giving the unit definition an optional human-readable name. Please see the next section for information about the values permitted for 'id'.

A UnitDefinition must contain exactly one ListOfUnits, and this list must contain one or more Unit definitions; see the definitions of these other object classes for more information about them. The following example illustrates a complete unit definition (when written in XML) when they all the pieces are combined together. This defines 'mmls' to be millimoles per litre per second. <listOfUnitDefinitions> <unitDefinition id="mmls"> <listOfUnits> <unit kind="mole" scale="-3"> <unit kind="litre" exponent="-1"> <unit kind="second" exponent="-1"> </listOfUnits> </unitDefinition> </listOfUnitDefinitions>

Special considerations for Unit object identifiers

The attribute 'id' in UnitDefinition cannot be given simply any value, and the precise details of the values permitted differ slightly between Levels of SBML:

  • The 'id' of a UnitDefinition must not contain a value from the list of SBML's predefined base unit names (i.e., the strings gram, litre, etc.). In SBML Level 3, this list consists of the following:

    amperefaradjouleluxradianvolt
    avogadrogramkatalmetresecondwatt
    becquerelgraykelvinmolesiemensweber
    candelahenrykilogramnewtonsievert
    coulombhertzlitreohmsteradian
    dimensionlessitemlumenpascaltesla

    This list of predefined base units is nearly identical in SBML Level 2 Version 4, the exception being that Level 2 does not define avogadro. SBML Level 2 Version 1 (and only this Level+Version combination) provides an additional predefined unit name, Celsius, not available in Level 3. Finally, SBML Level 1 Versions 2–3 provide two more additional predefined unit names, meter and liter. This is explained in somewhat greater detail in the description of the Unit class.

  • In SBML Level 2 (all Versions), there is an additional set of reserved identifiers: substance, volume, area, length, and time. Using one of these values for the attribute 'id' of a UnitDefinition has the effect of redefining the model-wide default units for the corresponding quantities. The list of special unit names in SBML Level 2 is given in the table below:

    Identifier Possible scalable units Default units
    substancemole, item, gram, kilogram, dimensionlessmole
    volumelitre, cubic metre, dimensionlesslitre
    areasquare metre, dimensionlesssquare metre
    lengthmetre, dimensionlessmetre
    timesecond, dimensionlesssecond

    Also, SBML Level 2 imposes two limitations on redefining the predefined unit substance, volume, area, length, and time: (1) The UnitDefinition of a predefined SBML unit can only contain a single Unit object within it. (2) The value of the 'kind' attribute in a Unit instance must be drawn from one of the values in the second column of the table above.

    The special unit names substance, volume, area, length, and time are not defined by SBML Level 3, which uses a different approach to setting model-wide inherited units.

Further comments about SBML's unit definition system

The vast majority of modeling situations requiring new SBML unit definitions involve simple multiplicative combinations of base units and factors. An example of this might be moles per litre per second. What distinguishes these sorts of simpler unit definitions from more complex ones is that they may be expressed without the use of an additive offset from a zero point. The use of offsets complicates all unit definition systems, yet in the domain of SBML the real-life cases requiring offsets are few (and in fact, to the best of our knowledge, only involve temperature). Consequently, the SBML unit system has been consciously designed in a way that attempts to simplify implementation of unit support for the most common cases in systems biology.

As of SBML Level 2 Version 2, Unit no longer has the attribute called 'offset' introduced in SBML Level 2 Version 1. It turned out that the general case involving units with offsets was incorrectly defined, and few (if any) developers even attempted to support offset-based units in their software. In the development of Level 2 Version 2, a consensus among SBML developers emerged that a fully generalized unit scheme is so confusing and complicated that it actually impedes interoperability. SBML Level 2 Version 2, Version 3 and Version 4 acknowledge this reality by reducing and simplifying the unit system, specifically by removing the 'offset' attribute on Unit and Celsius as a pre-defined unit.

The following guidelines suggest methods for handling units that do require the use of zero offsets for their definitions:

  • Handling Celsius. A model in which certain quantities are temperatures measured in degrees Celsius can be converted straightforwardly to a model in which those temperatures are in kelvin. A software tool could do this by performing a straightforward substitution using the following relationship: T kelvin = TCelsius + 273.15. In every mathematical formula of the model where a quantity (call it x) in degrees Celsius appears, replace x with xk+ 273.15, where xk is now in kelvin. An alternative approach would be to use a FunctionDefinition object to define a function encapsulating this relationship above and then using that in the rest of the model as needed. Since Celsius is a commonly-used unit, software tools could help users by providing users with the ability to express temperatures in Celsius in the tools' interfaces, and making substitutions automatically when writing out the SBML.

  • Other units requiring offsets. One approach to handling other kinds of units is to use a FunctionDefinition to define a function encapsulating the necessary mathematical relationship, then substituting a call to this function wherever the original quantity appeared in the model. For example, here is a possible definition for converting Fahrenheit to Celsius degrees: <functionDefinition id="Fahrenheit_to_kelvin"> <math xmlns="http://www.w3.org/1998/Math/MathML"> <lambda> <bvar><ci> temp_in_fahrenheit </ci></bvar> <apply> <divide> <apply> <plus> <ci> temp_in_fahrenheit </ci> <cn> 459.67 </cn> </apply> <cn> 1.8 </cn> </apply> </lambda> </math> </functionDefinition>

  • An alternative approach not requiring the use of function definitions is to use an AssignmentRule for each variable in Fahrenheit units. The AssignmentRule could compute the conversion from Fahrenheit to (say) kelvin, assign its value to a variable (in Kelvin units), and then that variable could be used elsewhere in the model.

  • Still another approach is to rewrite the mathematical formulas of a model to directly incorporate the conversion formula wherever the original quantity appeared.

Please consult the SBML specifications for more information about this and other issues involving units.

Constructor & Destructor Documentation

libsbmlcs.UnitDefinition.UnitDefinition ( long  level,
long  version 
)

Creates a new UnitDefinition using the given SBML level and version values.

Parameters
levela long integer, the SBML Level to assign to this UnitDefinition
versiona long integer, the SBML Version to assign to this UnitDefinition
Exceptions
SBMLConstructorExceptionThrown if the given level and version combination, or this kind of SBML object, are either invalid or mismatched with respect to the parent SBMLDocument object.
Note
Upon the addition of a UnitDefinition object to an SBMLDocument (e.g., using Model::addUnitDefinition()), the SBML Level, SBML Version and XML namespace of the document override the values used when creating the UnitDefinition object via this constructor. This is necessary to ensure that an SBML document is a consistent structure. Nevertheless, the ability to supply the values at the time of creation of a UnitDefinition is an important aid to producing valid SBML. Knowledge of the intented SBML Level and Version determine whether it is valid to assign a particular value to an attribute, or whether it is valid to add an object to an existing SBMLDocument.
libsbmlcs.UnitDefinition.UnitDefinition ( SBMLNamespaces  sbmlns)

Creates a new UnitDefinition using the given SBMLNamespaces object sbmlns.

The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core. A common approach to using this class constructor is to create an SBMLNamespaces object somewhere in a program, once, then pass it to object constructors such as this one when needed.

Parameters
sbmlnsan SBMLNamespaces object.
Exceptions
SBMLConstructorExceptionThrown if the given level and version combination, or this kind of SBML object, are either invalid or mismatched with respect to the parent SBMLDocument object.
Note
Upon the addition of a UnitDefinition object to an SBMLDocument (e.g., using Model::addUnitDefinition()), the SBML XML namespace of the document overrides the value used when creating the UnitDefinition object via this constructor. This is necessary to ensure that an SBML document is a consistent structure. Nevertheless, the ability to supply the values at the time of creation of a UnitDefinition is an important aid to producing valid SBML. Knowledge of the intented SBML Level and Version determine whether it is valid to assign a particular value to an attribute, or whether it is valid to add an object to an existing SBMLDocument.
libsbmlcs.UnitDefinition.UnitDefinition ( UnitDefinition  orig)

Copy constructor; creates a copy of this UnitDefinition.

Parameters
origthe object to copy.
Exceptions
SBMLConstructorExceptionThrown if the argument orig is null.

Member Function Documentation

int libsbmlcs.SBase.addCVTerm ( CVTerm  term,
bool  newBag 
)
inherited

Adds a copy of the given CVTerm object to this SBML object.

Parameters
termthe CVTerm to assign.
newBagif true, creates a new RDF bag with the same identifier as a previous bag, and if false, adds the term to an existing RDF bag with the same type of qualifier as the term being added.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
Since the CV Term uses the 'metaid' attribute of the object as a reference, if the object has no 'metaid' attribute value set, then the CVTerm will not be added.
Warning
The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained in this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance added here. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result.
int libsbmlcs.SBase.addCVTerm ( CVTerm  term)
inherited

Adds a copy of the given CVTerm object to this SBML object.

Parameters
termthe CVTerm to assign.
newBagif true, creates a new RDF bag with the same identifier as a previous bag, and if false, adds the term to an existing RDF bag with the same type of qualifier as the term being added.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
Since the CV Term uses the 'metaid' attribute of the object as a reference, if the object has no 'metaid' attribute value set, then the CVTerm will not be added.
Warning
The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained in this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance added here. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result.

uthe Unit instance to add to this UnitDefinition.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained in this UnitDefinition. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in the UnitDefinition. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result. Please see UnitDefinition::createUnit() for a method that does not lead to these issues.

int libsbmlcs.SBase.appendAnnotation ( XMLNode  annotation)
inherited

Appends the given annotation to the 'annotation' subelement of this object.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Unlike SBase::setAnnotation(XMLNode annotation) or SBase::setAnnotation(string annotation), this method allows other annotations to be preserved when an application adds its own data.

Parameters
annotationan XML structure that is to be copied and appended to the content of the 'annotation' subelement of this object
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

int libsbmlcs.SBase.appendNotes ( XMLNode  notes)
inherited

Appends the given notes to the 'notes' subelement of this object.

The content of notes is copied.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and  3 specifications have considerable detail about how 'notes' element content must be structured.

Parameters
notesan XML node structure that is to appended to the content of the 'notes' subelement of this object
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

static bool libsbmlcs.UnitDefinition.areEquivalent ( UnitDefinition  ud1,
UnitDefinition  ud2 
)
static

Predicate returning true if two UnitDefinition objects are equivalent.

For the purposes of performing this comparison, two UnitDefinition objects are considered equivalent when they contain equivalent list of Unit objects. Unit objects are in turn considered equivalent if they satisfy the predicate Unit::areEquivalent(). The predicate tests a subset of the objects's attributes.

Parameters
ud1the first UnitDefinition object to compare
ud2the second UnitDefinition object to compare
Returns
true if all the Unit objects in ud1 are equivalent to the Unit objects in ud2, false otherwise.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_areEquivalent(). They are functionally identical.

Unit::areEquivalent(Unit unit1, Unit unit2)
static bool libsbmlcs.UnitDefinition.areIdentical ( UnitDefinition  ud1,
UnitDefinition  ud2 
)
static

Predicate returning true if two UnitDefinition objects are identical.

For the purposes of performing this comparison, two UnitDefinition objects are considered identical when they contain identical lists of Unit objects. Pairs of Unit objects in the lists are in turn considered identical if they satisfy the predicate Unit::areIdentical(). The predicate compares every attribute of the Unit objects.

Parameters
ud1the first UnitDefinition object to compare
ud2the second UnitDefinition object to compare
Returns
true if all the Unit objects in ud1 are identical to the Unit objects of ud2, false otherwise.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_areIdentical(). They are functionally identical.

new UnitDefinition libsbmlcs.UnitDefinition.clone ( )

Creates and returns a deep copy of this UnitDefinition.

Returns
a (deep) copy of this UnitDefinition.
static UnitDefinition libsbmlcs.UnitDefinition.combine ( UnitDefinition  ud1,
UnitDefinition  ud2 
)
static

Combines two UnitDefinition objects into a single UnitDefinition.

This takes UnitDefinition objects ud1 and ud2, and creates a UnitDefinition object that expresses the product of the units of ud1 and ud2.

Parameters
ud1the first UnitDefinition object
ud2the second UnitDefinition object
Returns
a UnitDefinition which represents the product of the units of the two argument UnitDefinitions.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_combine(). They are functionally identical.
void libsbmlcs.SBase.connectToParent ( SBase  parent)
inherited

Sets the parent SBML object of this SBML object.

(Creates a child-parent relationship by the child) This function is called when a child element is set/added/created by its parent element (e.g. by setXXX, addXXX, createXXX, and connectToChild functions of the parent element).

Parameters
parentthe SBML object to use
static UnitDefinition libsbmlcs.UnitDefinition.convertToSI ( UnitDefinition  ud)
static

Convert a given UnitDefinition into a new UnitDefinition object that uses SI units.

Parameters
udthe UnitDefinition object to convert to SI
Returns
a new UnitDefinition object representing the results of the conversion.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_convertToSI(). They are functionally identical.
Unit libsbmlcs.UnitDefinition.createUnit ( )

Creates a new and empty Unit, adds it to this UnitDefinition's list of units, and returns it.

Returns
a newly constructed (and empty) Unit instance.
Note
It is worth emphasizing that the attribute 'kind' value of a Unit is a required attribute for a valid Unit definition. The createUnit() method does not assign a valid kind to the constructed unit (instead, it sets the 'kind' to UNIT_KIND_INVALID). Callers are cautioned to set the newly-constructed Unit's kind using Unit::setKind() soon after calling this method.

SBase libsbmlcs.SBase.getAncestorOfType ( int  type,
string  pkgName 
)
inherited

Returns the first ancestor object that has the given SBML type code.

LibSBML attaches an identifying code to every kind of SBML object. These are known as SBML type codes. In the C# language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. The names of the type codes all begin with the characters SBML_.

This method searches the tree of objects that are parents of this object, and returns the first one that has the given SBML type code. If the optional argument pkgName is given, it will cause the search to be limited to the SBML Level 3 package given.

Parameters
typethe SBML type code of the object sought
pkgName(optional) the short name of an SBML Level 3 package to which the sought-after object must belong
Returns
the ancestor SBML object of this SBML object that corresponds to the given SBML object type code, or null if no ancestor exists.

XMLNode libsbmlcs.SBase.getAnnotation ( )
inherited

Returns the content of the 'annotation' subelement of this object as a tree of XMLNode objects.

Whereas the SBML 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

The annotations returned by this method will be in XML form. LibSBML provides an object model and related interfaces for certain specific kinds of annotations, namely model history information and RDF content. See the ModelHistory, CVTerm and RDFAnnotationParser classes for more information about the facilities available.

long libsbmlcs.SBase.getColumn ( )
inherited

Returns the column number on which this object first appears in the XML representation of the SBML document.

Returns
the column number of this SBML object.
Note
The column number for each construct in an SBML model is set upon reading the model. The accuracy of the column number depends on the correctness of the XML representation of the model, and on the particular XML parser library being used. The former limitation relates to the following problem: if the model is actually invalid XML, then the parser may not be able to interpret the data correctly and consequently may not be able to establish the real column number. The latter limitation is simply that different parsers seem to have their own accuracy limitations, and out of all the parsers supported by libSBML, none have been 100% accurate in all situations. (At this time, libSBML supports the use of libxml2, Expat and Xerces.)

string libsbmlcs.SBase.getMetaId ( )
inherited

Returns the value of the 'metaid' attribute of this object.

The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Returns

XMLNode libsbmlcs.SBase.getNotes ( )
inherited

Returns the content of the 'notes' subelement of this object as a tree of XMLNode objects.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and  3 specifications have considerable detail about how 'notes' element content must be structured.

The 'notes' element content returned by this method will be in XML form, but libSBML does not provide an object model specifically for the content of notes. Callers will need to traverse the XML tree structure using the facilities available on XMLNode and related objects. For an alternative method of accessing the notes, see getNotesString().

int libsbmlcs.SBase.getResourceBiologicalQualifier ( string  resource)
inherited

Returns the MIRIAM biological qualifier associated with the given resource.

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml.

This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose names begin with BQB_ in the interface class libsbml.

Parameters
resourcestring representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'.
Returns
the qualifier associated with the resource, or BQB_UNKNOWN if the resource does not exist.
Note
The set of MIRIAM biological qualifiers grows over time, although relatively slowly. The values are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQB_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.
int libsbmlcs.SBase.getResourceModelQualifier ( string  resource)
inherited

Returns the MIRIAM model qualifier associated with the given resource.

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is 'isDerivedFrom', to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml.

This method method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have model qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of type of model qualifier associated with that resource as a valuewhose names begin with BQB_ in the interface class libsbml.

Parameters
resourcestring representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'.
Returns
the model qualifier type associated with the resource, or BQM_UNKNOWN if the resource does not exist.
Note
The set of MIRIAM model qualifiers grows over time, although relatively slowly. The values are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQM_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.
SBMLDocument libsbmlcs.SBase.getSBMLDocument ( )
inherited

Returns the SBMLDocument object containing this object instance.

LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)

This method allows the caller to obtain the SBMLDocument for the current object.

Returns
the parent SBMLDocument object of this SBML object.

getModel()
SBMLNamespaces libsbmlcs.SBase.getSBMLNamespaces ( )
inherited

Subclasses should override this method to write out their contained SBML objects as XML elements.

Be sure to call your parents implementation of this method as well. For example:

int libsbmlcs.SBase.getSBOTerm ( )
inherited

Returns the integer portion of the value of the 'sboTerm' attribute of this object.

Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers. (For convenience, libSBML offers methods for returning both the integer form and a text-string form of the SBO identifier.)

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Returns
the value of the 'sboTerm' attribute as an integer, or -1 if the value is not set.
string libsbmlcs.SBase.getSBOTermAsURL ( )
inherited

Returns the identifiers.org URL representation of the 'sboTerm' attribute of this object.

This method returns the entire SBO identifier as a text string in the form 'http://identifiers.org/biomodels.sbo/SBO:NNNNNNN'.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Returns
the value of the 'sboTerm' attribute as an identifiers.org URL (its value will be of the form 'http://identifiers.org/biomodels.sbo/SBO:NNNNNNN'), or an empty string if the value is not set.
string libsbmlcs.SBase.getSBOTermID ( )
inherited

Returns the string representation of the 'sboTerm' attribute of this object.

Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers. This method returns the entire SBO identifier as a text string in the form 'SBO:NNNNNNN'.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Returns
the value of the 'sboTerm' attribute as a string (its value will be of the form 'SBO:NNNNNNN'), or an empty string if the value is not set.
new int libsbmlcs.UnitDefinition.getTypeCode ( )

Returns the libSBML type code for this object instance.

LibSBML attaches an identifying code to every kind of SBML object. These are known as SBML type codes. In the C# language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbmlcs.libsbml. The names of the type codes all begin with the characters SBML_.

Returns
the SBML type code for this object, or SBML_UNKNOWN (default).

Returns
a bool value indicating whether all the required attributes for this object have been defined.
new bool libsbmlcs.UnitDefinition.hasRequiredElements ( )

Predicate returning true if all the required elements for this UnitDefinition object have been set.

Note
The required elements for a Constraint object are:

isPkgEnabled()
bool libsbmlcs.SBase.isSetAnnotation ( )
inherited

Predicate returning true if this object's 'annotation' subelement exists and has content.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Returns
true if a 'annotation' subelement exists, false otherwise.

new bool libsbmlcs.UnitDefinition.isSetId ( )

Predicate returning true if this UnitDefinition's 'id' attribute is set.

Returns
true if the 'id' attribute of this UnitDefinition is set, false otherwise.
bool libsbmlcs.SBase.isSetMetaId ( )
inherited

Predicate returning true if this object's 'metaid' attribute is set.

The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Returns
true if the 'metaid' attribute of this SBML object is set, false otherwise.
See Also
getMetaId()
setMetaId(string metaid)
bool libsbmlcs.SBase.isSetModelHistory ( )
inherited

Predicate returning true if this object has a ModelHistory object attached to it.

Returns
true if the ModelHistory of this object is set, false otherwise.
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
new bool libsbmlcs.UnitDefinition.isSetName ( )

Predicate returning true if this UnitDefinition's 'name' attribute is set.

Returns
true if the 'name' attribute of this UnitDefinition is set, false otherwise.
bool libsbmlcs.SBase.isSetNotes ( )
inherited

Predicate returning true if this object's 'notes' subelement exists and has content.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and  3 specifications have considerable detail about how 'notes' element content must be structured.

Returns
true if a 'notes' subelement exists, false otherwise.

int libsbmlcs.SBase.prependStringToAllIdentifiers ( string  prefix)
inherited

Add the given string to all identifiers in the object.

If the string is added to anything other than an id or a metaid, this code is responsible for tracking down and renaming all *idRefs in the package extention that identifier comes from.

static string libsbmlcs.UnitDefinition.printUnits ( UnitDefinition  ud,
bool  compact 
)
static

Expresses the given definition in a plain-text form.

For example, UnitDefinition::printUnits() applied to <unitDefinition> <listOfUnits> <unit kind="metre" exponent="1"> <unit kind="second" exponent="-2"> </listOfUnits> <unitDefinition> will return the string 'metre (exponent = 1, multiplier = 1, scale = 0) second (exponent = -2, multiplier = 1, scale = 0)' or, if the optional parameter compact is given the value true, the string '(1 metre)^1 (1 second)^-2'. This method may be useful for printing unit information to human users, or in debugging software, or other situations.

Parameters
udthe UnitDefinition object
compactbool indicating whether the compact form should be used (defaults to false)
Returns
a string expressing the unit definition defined by the given UnitDefinition object ud.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_printUnits(). They are functionally identical.
static string libsbmlcs.UnitDefinition.printUnits ( UnitDefinition  ud)
static

Expresses the given definition in a plain-text form.

For example, UnitDefinition::printUnits() applied to <unitDefinition> <listOfUnits> <unit kind="metre" exponent="1"> <unit kind="second" exponent="-2"> </listOfUnits> <unitDefinition> will return the string 'metre (exponent = 1, multiplier = 1, scale = 0) second (exponent = -2, multiplier = 1, scale = 0)' or, if the optional parameter compact is given the value true, the string '(1 metre)^1 (1 second)^-2'. This method may be useful for printing unit information to human users, or in debugging software, or other situations.

Parameters
udthe UnitDefinition object
compactbool indicating whether the compact form should be used (defaults to false)
Returns
a string expressing the unit definition defined by the given UnitDefinition object ud.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_printUnits(). They are functionally identical.
int libsbmlcs.SBase.removeFromParentAndDelete ( )
inherited

Removes itself from its parent.

If the parent was storing it as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). Pure virutal, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.removeTopLevelAnnotationElement ( string  elementName,
string  elementURI 
)
inherited

Removes the top-level element within the 'annotation' subelement of this SBML object with the given name and optional URI.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Calling this method allows a particular annotation element to be removed whilst the remaining annotations remain intact.

Parameters
elementNamea string representing the name of the top level annotation element that is to be removed

void libsbmlcs.SBase.renameMetaIdRefs ( string  oldid,
string  newid 
)
inherited

Renames all the MetaIdRef attributes on this element.

This method works by looking at all meta-attribute values, comparing the identifiers to the value of oldid. If any matches are found, the matching identifiers are replaced with newid. The method does not descend into child elements.

Parameters
oldidthe old identifier
newidthe new identifier
void libsbmlcs.SBase.renameUnitSIdRefs ( string  oldid,
string  newid 
)
inherited

Renames all the UnitSIdRef attributes on this element.

static void libsbmlcs.UnitDefinition.reorder ( UnitDefinition  ud)
static

Alphabetically orders the Unit objects within the ListOfUnits of a UnitDefinition.

Parameters
udthe UnitDefinition object whose units are to be reordered.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_reorder(). They are functionally identical.
void libsbmlcs.SBase.replaceSIDWithFunction ( string  id,
ASTNode  function 
)
inherited

If this object has a child 'math' object (or anything with ASTNodes in general), replace all nodes with the name 'id' with the provided function.

Note
This function does nothing itself—subclasses with ASTNode subelements must override this function.
int libsbmlcs.SBase.replaceTopLevelAnnotationElement ( XMLNode  annotation)
inherited

Replaces the given top-level element within the 'annotation' subelement of this SBML object and with the annotation element supplied.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

This method determines the name of the element to be replaced from the annotation argument. Functionally it is equivalent to calling removeTopLevelAnnotationElement(name); appendAnnotation(annotation_with_name); with the exception that the placement of the annotation element remains the same.

Parameters

int libsbmlcs.SBase.setAnnotation ( XMLNode  annotation)
inherited

Sets the value of the 'annotation' subelement of this SBML object.

The content of annotation is copied, and any previous content of this object's 'annotation' subelement is deleted.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Call this method will result in any existing content of the 'annotation' subelement to be discarded. Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded. An alternative may be to use SBase::appendAnnotation(XMLNode annotation) or SBase::appendAnnotation(string annotation).

Parameters
annotationan XML structure that is to be used as the new content of the 'annotation' subelement of this object
Returns

new int libsbmlcs.UnitDefinition.setId ( string  sid)

Sets the value of the 'id' attribute of this UnitDefinition.

The string sid is copied. Note that SBML has strict requirements for the syntax of identifiers. The following is a summary of the definition of the SBML identifier type SId, which defines the permitted syntax of identifiers. We express the syntax using an extended form of BNF notation:

letter ::= 'a'..'z','A'..'Z'
digit  ::= '0'..'9'
idChar ::= letter | digit | '_'
SId    ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * "zero or more times", and the character | indicates logical "or". The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. In addition, there are a few conditions for the uniqueness of identifiers in an SBML model. Please consult the SBML specifications for the exact formulations.

Parameters
sidthe string to use as the identifier of this UnitDefinition
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.setMetaId ( string  metaid)
inherited

Sets the value of the 'metaid' attribute of this object.

The string metaid is copied. The value of metaid must be an identifier conforming to the syntax defined by the XML 1.0 data type ID. Among other things, this type requires that a value is unique among all the values of type XML ID in an SBMLDocument. Although SBML only uses XML ID for the 'metaid' attribute, callers should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement.

Parameters
metaidthe identifier string to use as the value of the 'metaid' attribute
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

Parameters
historyModelHistory of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
new int libsbmlcs.UnitDefinition.setName ( string  name)

Sets the value of the 'name' attribute of this UnitDefinition.

The string in name is copied.

Parameters
namethe new name for the UnitDefinition
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

inherited

Sets the namespaces relevant of this SBML object.

The content of xmlns is copied, and this object's existing namespace content is deleted.

The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core.

Parameters
xmlnsthe namespaces to set
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.setNotes ( XMLNode  notes)
inherited

Sets the value of the 'notes' subelement of this SBML object.

The content of notes is copied, and any existing content of this object's 'notes' subelement is deleted.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and  3 specifications have considerable detail about how 'notes' element content must be structured.

Parameters
notesan XML structure that is to be used as the content of the 'notes' subelement of this object
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component. SBMLDocument s = new SBMLDocument(3, 1); s.setNotes('<body xmlns="http://www.w3.org/1999/xhtml">

here is my note

</body>');

Parameters
notesan XML string that is to be used as the content of the 'notes' subelement of this object
addXHTMLMarkupa bool indicating whether to wrap the contents of the notes argument with XHTML paragraph (<p>) tags. This is appropriate when the string in notes does not already containg the appropriate XHTML markup.

void libsbmlcs.SBase.setSBMLNamespacesAndOwn ( SBMLNamespaces  sbmlns)
inherited

Subclasses should override this method to write out their contained SBML objects as XML elements.

Be sure to call your parents implementation of this method as well. For example:

int libsbmlcs.SBase.setSBOTerm ( int  value)
inherited

Sets the value of the 'sboTerm' attribute.

Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Parameters
valuethe NNNNNNN integer portion of the SBO identifier
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
See Also
setSBOTerm(string sboid)
int libsbmlcs.SBase.setSBOTerm ( string  sboid)
inherited

Sets the value of the 'sboTerm' attribute by string.

Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers. This method lets you set the value of 'sboTerm' as a complete string of the form 'SBO:NNNNNNN', whereas setSBOTerm(int value) allows you to set it using the integer form.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Parameters
sboidthe SBO identifier string of the form 'SBO:NNNNNNN'
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

setSBOTerm(int value)
static void libsbmlcs.UnitDefinition.simplify ( UnitDefinition  ud)
static

Simplifies the UnitDefinition such that any given kind of Unit object occurs only once in the ListOfUnits.

For example, the following definition, <unitDefinition> <listOfUnits> <unit kind="metre" exponent="1"> <unit kind="metre" exponent="2"> </listOfUnits> <unitDefinition> will be simplified to <unitDefinition> <listOfUnits> <unit kind="metre" exponent="3"> </listOfUnits> <unitDefinition>

Parameters
udthe UnitDefinition object to be simplified.
Note
Because this is a static method, the non-C++ language interfaces for libSBML will contain two variants. One will be a static method on the class (i.e., UnitDefinition), and the other will be a standalone top-level function with the name UnitDefinition_simplify(). They are functionally identical.
string libsbmlcs.SBase.toSBML ( )
inherited

Returns a string consisting of a partial SBML corresponding to just this object.

Returns
the partial SBML that describes this SBML object.
Warning
This is primarily provided for testing and debugging purposes. It may be removed in a future version of libSBML.
int libsbmlcs.SBase.unsetAnnotation ( )
inherited

Unsets the value of the 'annotation' subelement of this SBML object.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
See Also
getAnnotation()
getAnnotationString()
isSetAnnotation()
setAnnotation(XMLNode annotation)
setAnnotation(string annotation)
appendAnnotation(XMLNode annotation)
appendAnnotation(string annotation)
int libsbmlcs.SBase.unsetCVTerms ( )
inherited

Clears the list of CVTerm objects attached to this SBML object.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.unsetId ( )
inherited

Unsets the value of the 'id' attribute of this SBML object.

Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always either Sid or UnitSId, depending on the object in question. Both data types are defined as follows:

  letter ::= 'a'..'z','A'..'Z'
  digit  ::= '0'..'9'
  idChar ::= letter | digit | '_'
  SId    ::= ( letter | '_' ) idChar*

The equality of SId and UnitSId type values in SBML is determined by an exact character sequence match; i.e., comparisons of these identifiers must be performed in a case-sensitive manner. This applies to all uses of SId and UnitSId.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.unsetMetaId ( )
inherited

Unsets the value of the 'metaid' attribute of this SBML object.

The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.unsetModelHistory ( )
inherited

Unsets the ModelHistory object attached to this object.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
new int libsbmlcs.UnitDefinition.unsetName ( )

Unsets the value of the 'name' attribute of this UnitDefinition.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
int libsbmlcs.SBase.unsetNotes ( )
inherited

Unsets the value of the 'notes' subelement of this SBML object.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and  3 specifications have considerable detail about how 'notes' element content must be structured.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

int libsbmlcs.SBase.unsetSBOTerm ( )
inherited

Unsets the value of the 'sboTerm' attribute of this SBML object.

void libsbmlcs.SBase.writeExtensionElements ( XMLOutputStream  stream)
inherited
