An SBML algebraic rule representing 0 = f(W).The rule type AlgebraicRule is derived from the parent class Rule. It is used to express equations that are neither assignments of model variables nor rates of change. AlgebraicRule does not add any attributes to the basic Rule; its role is simply to distinguish this case from the other cases.
In the context of a simulation, algebraic rules are in effect at all times, t >= 0. For purposes of evaluating expressions that involve the delay 'csymbol' (see the SBML specification), algebraic rules are considered to apply also at t <= 0. Please consult the relevant SBML specification for additional information about the semantics of assignments, rules, and entity values for simulation time t <= 0.
An SBML model must not be overdetermined. The ability to define arbitrary algebraic expressions in an SBML model introduces the possibility that a model is mathematically overdetermined by the overall system of equations constructed from its rules, reactions and events. Therefore, if an algebraic rule is introduced in a model, for at least one of the entities referenced in the rule's 'math' element the value of that entity must not be completely determined by other constructs in the model. This means that at least this entity must not have the attribute 'constant'=true
and there must also not be a rate rule or assignment rule for it. Furthermore, if the entity is a Species object, its value must not be determined by reactions, which means that it must either have the attribute 'boundaryCondition'=true
or else not be involved in any reaction at all. These restrictions are explained in more detail in the SBML specification documents.
In SBML Levels 2 and 3, Reaction object identifiers can be referenced in the 'math' expression of an algebraic rule, but reaction rates can never be determined by algebraic rules. This is true even when a reaction does not contain a KineticLaw object. (In such cases of missing kinetic law definitions, the model is valid but incomplete; the rates of reactions lacking kinetic laws are simply undefined, and not determined by the algebraic rule.)
In SBML Level 3 as well as Level 2, rules are separated into three subclasses for the benefit of model analysis software. The three subclasses are based on the following three different possible functional forms (where x is a variable, f is some arbitrary function returning a numerical result, V is a vector of variables that does not include x, and W is a vector of variables that may include x):
Algebraic: | left-hand side is zero | 0 = f(W) |
Assignment: | left-hand side is a scalar: | x = f(V) |
Rate: | left-hand side is a rate-of-change: | dx/dt = f(W) |
In their general form given above, there is little to distinguish between assignment and algebraic rules. They are treated as separate cases for the following reasons:
The approach taken to covering these cases in SBML is to define an abstract Rule structure containing a subelement, 'math', to hold the right-hand side expression, then to derive subtypes of Rule that add attributes to distinguish the cases of algebraic, assignment and rate rules. The 'math' subelement must contain a MathML expression defining the mathematical formula of the rule. This MathML formula must return a numerical value. The formula can be an arbitrary expression referencing the variables and other entities in an SBML model.
Each of the three subclasses of Rule (AssignmentRule, AlgebraicRule, RateRule) inherit the the 'math' subelement and other fields from SBase. The AssignmentRule and RateRule classes add an additional attribute, 'variable'. See the definitions of AssignmentRule, AlgebraicRule and RateRule for details about the structure and interpretation of each one.
An important design goal of SBML rule semantics is to ensure that a model's simulation and analysis results will not be dependent on when or how often rules are evaluated. To achieve this, SBML needs to place two restrictions on rule use. The first concerns algebraic loops in the system of assignments in a model, and the second concerns overdetermined systems.
The combined set of InitialAssignment, AssignmentRule and KineticLaw objects in a model constitute a set of assignment statements that should be considered as a whole. (A KineticLaw object is counted as an assignment because it assigns a value to the symbol contained in the 'id' attribute of the Reaction object in which it is defined.) This combined set of assignment statements must not contain algebraic loops—dependency chains between these statements must terminate. To put this more formally, consider a directed graph in which nodes are assignment statements and directed arcs exist for each occurrence of an SBML species, compartment or parameter symbol in an assignment statement's 'math' subelement. Let the directed arcs point from the statement assigning the symbol to the statements that contain the symbol in their 'math' subelement expressions. This graph must be acyclic.
SBML does not specify when or how often rules should be evaluated. Eliminating algebraic loops ensures that assignment statements can be evaluated any number of times without the result of those evaluations changing. As an example, consider the set of equations x = x + 1, y = z + 200 and z = y + 100. If this set of equations were interpreted as a set of assignment statements, it would be invalid because the rule for x refers to x (exhibiting one type of loop), and the rule for y refers to z while the rule for z refers back to y (exhibiting another type of loop). Conversely, the following set of equations would constitute a valid set of assignment statements: x = 10, y = z + 200, and z = x + 100.
An SBML model must not be overdetermined; that is, a model must not define more equations than there are unknowns in a model. An SBML model that does not contain AlgebraicRule structures cannot be overdetermined.
LibSBML implements the static analysis procedure described in Appendix B of the SBML Level 3 Version 1 Core specification for assessing whether a model is overdetermined.
(In summary, assessing whether a given continuous, deterministic, mathematical model is overdetermined does not require dynamic analysis; it can be done by analyzing the system of equations created from the model. One approach is to construct a bipartite graph in which one set of vertices represents the variables and the other the set of vertices represents the equations. Place edges between vertices such that variables in the system are linked to the equations that determine them. For algebraic equations, there will be edges between the equation and each variable occurring in the equation. For ordinary differential equations (such as those defined by rate rules or implied by the reaction rate definitions), there will be a single edge between the equation and the variable determined by that differential equation. A mathematical model is overdetermined if the maximal matchings of the bipartite graph contain disconnected vertexes representing equations. If one maximal matching has this property, then all the maximal matchings will have this property; i.e., it is only necessary to find one maximal matching.)
SBML Level 1 uses a different scheme than SBML Level 2 and Level 3 for distinguishing rules; specifically, it uses an attribute whose value is drawn from an enumeration of 3 values. LibSBML supports this using methods that work with the enumeration values listed below.

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.

SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.
If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.

If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.

Disables the given SBML Level 3 package on this object.
This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.
An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:
pkgURI | the URI of the package |
pkgPrefix | the XML prefix of the package |

Reimplemented from libsbmlcs.SBase.

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.

Returns the nth disabled plug-in object (extension interface) for an SBML Level 3 package extension.
SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.

Returns the first child element it can find with a specific 'metaid' attribute value, or null
if no such object is found.
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. The latter point is important, because the uniqueness criterion applies across any attribute with type ID
anywhere in the file, 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 the XML ID
type. Although SBML itself specifies the use of XML ID
only for the 'metaid' attribute, SBML-compatible applications 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. Finally, note that LibSBML does not provide an explicit XML ID
data type; it uses ordinary character strings, which is easier for applications to support.

Returns the SBML Level of the SBMLDocument object containing this object.
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.)

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 (and in SBML Level 3, the 'message' subelement of Constraint), 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 conform to the definition of XHTML 1.0. However, the content cannot be entirely free-form; it must satisfy certain requirements defined in the SBML specifications for specific SBML Levels. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); this method implements a verification process that lets callers check whether the content of a given XMLNode object conforms to the SBML requirements for 'notes' and 'message' structure. Developers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations of using 'notes' in SBML. 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().

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

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'.

In order to make it easier for application developers to work with all Levels of SBML, libSBML uses a uniform name for all such attributes, and it is 'variable', regardless of whether Level 1 rules or Level 2–3 rules are being used.

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. The latter point is important, because the uniqueness criterion applies across any attribute with type ID
anywhere in the file, 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 the XML ID
type. Although SBML itself specifies the use of XML ID
only for the 'metaid' attribute, SBML-compatible applications 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. Finally, note that LibSBML does not provide an explicit XML ID

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.

Predicate returning true
if this Rule's 'variable' attribute is set.
In SBML Level 1, the different rule types each have a different name for the attribute holding the reference to the object constituting the left-hand side of the rule. (E.g., for SBML Level 1's SpeciesConcentrationRule the attribute is 'species', for CompartmentVolumeRule it is 'compartment', etc.) In SBML Levels 2 and 3, the only two types of Rule objects with a left-hand side object reference are AssignmentRule and RateRule, and both of them use the same name for attribute: 'variable'. In order to make it easier for application developers to work with all Levels of SBML, libSBML uses a uniform name for all such attributes, and it is 'variable', regardless of whether Level 1 rules or Level 2–3 rules are being used.
true

This libSBML method works for SBML Level 1 models (where there is such a thing as an explicit SpeciesConcentrationRule), as well as other Levels of SBML. For Levels above Level 1, this method checks the symbol being affected by the rule, and returns true

Removes this object from its parent.
If the parent was storing this object as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). This is a pure virtual method, 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.

Replaces all uses of a given meta identifier attribute value with another value.
In SBML, object 'meta' identifiers are of the XML data type ID
; the SBML object attribute itself is typically named metaid
. All attributes that hold values referring to values of type ID
are of the XML data type IDREF
. They are also sometimes informally referred to as 'metaid refs', in analogy to the SBML-defined type SIdRef
.
This method works by looking at all meta-identifier 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.

Replaces all uses of a given SIdRef
type attribute value with another value.
In SBML, object identifiers are of a data type called SId
. In SBML Level 3, an explicit data type called SIdRef
was introduced for attribute values that refer to SId
values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as 'referring to an identifier', but the effective data type was the same as SIdRef
in Level 3. These and other methods of libSBML refer to the type SIdRef
for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.
This method works by looking at all attributes and (if appropriate) mathematical formulas in MathML content, comparing the referenced identifiers to the value of oldid

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

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'.

Unsets the value of the 'name' attribute of this SBML object.
Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. In contrast to the 'id' attribute, the 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string
defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string
type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
