This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.
The function SBML_parseL3FormulaWithSettings(), along with its variants SBML_parseL3Formula() and SBML_parseL3FormulaWithModel(), are the interfaces to a parser for mathematical formulas written as text strings. The inverse function is SBML_formulaToL3String() and its variants such as SBML_formulaToL3StringWithSettings(). The parsers and the formula writers convert between a text-string representation of mathematical formulas and Abstract Syntax Trees (ASTs), represented in libSBML using ASTNode objects. Compared to the parser and writer implemented by the functions SBML_parseFormula() and SBML_formulaToString(), which were designed primarily for converting the mathematical formula strings in SBML Level 1, the SBML Level 3 or 'L3' variants of the parser and writer use an extended formula syntax. They also have a number of configurable behaviors. This class (L3ParserSettings) is an object used to communicate the configuration settings with callers.
The following aspects of the parser are configurable using L3ParserSettings objects. (For the formula writer, only a subset of these settings is relevant; please see the documentation for SBML_formulaToL3StringWithSettings() for more information about which ones).
SId) from the model in preference to pre-defined MathML symbols More precisely, the Model entities whose identifiers will shadow identical symbols in the mathematical formula are: Species, Compartment, Parameter, Reaction, and SpeciesReference. For instance, if the parser is given a Model containing a Species with the identifier "pi", and the formula to be parsed is "3*pi", the MathML produced by the parser will contain the construct <ci> pi </ci> instead of the construct <pi/>. Another example, if the passed-in Model contains a FunctionDefinition with the identifier "sin", that function will be used instead of the predefined MathML function <sin/>. log with a single argument ("log(x)") can be parsed as log10(x), ln(x), or treated as an error, as desired. - -3") from the input and incorporate single unary minuses into the number node, or (2) preserve all minuses in the AST node structure, turning them into ASTNode objects of type AST_MINUS. number id" can be interpreted as a numerical value number followed by units of measurement indicated by id, or it can be treated as a syntax error. (In Level 3, MathML <cn> elements can have an attribute named units placed in the SBML namespace, which can be used to indicate the units to be associated with the number. The text-string infix formula parser allows units to be placed after raw numbers; they are interpreted as unit identifiers for units defined by the SBML specification or in the containing Model object.) avogadro can be parsed either as a MathML csymbol or as a identifier. More specifically, "avogadro" can be treated as an ASTNode of type AST_NAME_AVOGADRO or of type AST_NAME. To obtain the default configuration values, callers can use the function SBML_getDefaultL3ParserSettings(). To change the configuration, callers can create an L3ParserSettings object, set the desired characteristics using the methods provided, and pass that object to SBML_parseL3FormulaWithSettings().

Creates a new L3ParserSettings object with default values.
This is the default constructor for the L3ParserSettings object. It sets the stored Model object to null and sets the following field values in the L3ParserSettings object:
null (which indicates that no syntax extensions due to SBML Level 3 packages will be assumed—the formula parser will only understand the core syntax described in the documentation for SBML_parseL3Formula()). | libsbmlcs.L3ParserSettings.L3ParserSettings | ( | Model | model, |

Creates a new L3ParserSettings object with specific values for all possible settings.
| model | a Model object to be used for disambiguating identifiers encountered by SBML_parseL3FormulaWithSettings() in mathematical formulas. |
| parselog | ('parse log') a flag that controls how the parser will handle the symbol log in mathematical formulas. The function log with a single argument ("log(x)") can be parsed as log10(x), ln(x), or treated as an error, as desired, by using the parameter values L3P_PARSE_LOG_AS_LOG10, L3P_PARSE_LOG_AS_LN, or L3P_PARSE_LOG_AS_ERROR, respectively. |
| collapseminus | ('collapse minus') a flag that controls how the parser will handle minus signs in formulas. Unary minus signs can be collapsed or preserved; that is, sequential pairs of unary minuses (e.g., "- -3") can be removed from the input entirely and single unary minuses can be incorporated into the number node, or all minuses can be preserved in the AST node structure. The possible values of this field are L3P_COLLAPSE_UNARY_MINUS (to collapse unary minuses) and L3P_EXPAND_UNARY_MINUS (to expand unary minuses). |
| parseunits | ('parse units') a flag that controls how the parser will handle apparent references to units of measurement associated with raw numbers in a formula. If set to the value L3P_PARSE_UNITS, units are parsed; if set to the value L3P_NO_UNITS, units are not parsed. |
| avocsymbol | ('Avogadro csymbol') a flag that controls how the parser will handle the appearance of the symbol avogadro in a formula. If set to the value L3P_AVOGADRO_IS_CSYMBOL, the symbol is interpreted as the SBML/MathML csymbol avogadro; if set to the value L3P_AVOGADRO_IS_NAME, the symbol is interpreted as a plain symbol name. |
| caseSensitive | ('case sensitive') a flag that controls how the cases of alphabetical characters are treated when symbols are compared. If the flag is set to the value L3P_COMPARE_BUILTINS_CASE_INSENSITIVE, symbols are compared in a case-insensitive manner, which means that mathematical functions such as 'sin' will be matched no matter what their case is: 'Sin', 'SIN', etc. If the flag is set to the value L3P_COMPARE_BUILTINS_CASE_SENSITIVE, symbols are interpreted in a case-sensitive manner. |
| moduloL3v2 | ('modulo l3v2') a flag that controls how the parser will handle the '' ('modulo') symbol in formulas. By default, the parser will convert 'a % b' to a piecewise function that properly calculates the remainder of a with respect to be, but the parser can also be set to produce the MathML rem function, should the target of the produced ASTNode be an SBML Level 3 Version 2 document, where the rem function is legal. The possible values of this field are L3P_MODULO_IS_PIECEWISE (to parse '' as a piecewise function) and L3P_MODULO_IS_REM (to parse '' as rem). |
| sbmlns | ('SBML namespaces') an SBML namespaces object. The namespaces identify the SBML Level 3 packages that can extend the syntax understood by the formula parser. When non-null, the parser will interpret additional syntax defined by the packages; for example, it may understand vector/array extensions introduced by the SBML Level 3 Arrays package. |

| source | the instance to copy. |
|

| bool libsbmlcs.L3ParserSettings.getComparisonCaseSensitivity | ( | ) |
Returns true if the parser is configured to match built-in symbols in a case-insensitive way.
By default (which is the value L3P_COMPARE_BUILTINS_CASE_INSENSITIVE), the parser compares symbols in a case insensitive manner for built-in functions such as 'sin' and 'piecewise', and for constants such as 'true' and 'avogadro'. Setting this option to L3P_COMPARE_BUILTINS_CASE_SENSITIVE causes the parser to become case sensitive. In that mode, for example, the symbols 'sin' and 'true' will match the built-in values, but the symbols 'SIN', 'Sin', 'True', 'TRUE', and so on, will not.
true if matches are done in a case-sensitive manner, and false if the parser will recognize built-in functions and constants regardless of case,.| Model libsbmlcs.L3ParserSettings.getModel | ( | ) |
Returns the Model object referenced by this L3ParserSettings object.
When a Model object is provided, identifiers (values of type SId) from that model are used in preference to pre-defined MathML symbol definitions. More precisely, the Model entities whose identifiers will shadow identical symbols in the mathematical formula are: Species, Compartment, Parameter, Reaction, and SpeciesReference. For instance, if the parser is given a Model containing a Species with the identifier "pi", and the formula to be parsed is "3*pi", the MathML produced will contain the construct <ci> pi </ci> instead of the construct <pi/>. Similarly, when a Model object is provided, SId values of user-defined functions present in the Model will be used preferentially over pre-defined MathML functions. For example, if the passed-in Model contains a FunctionDefinition with the identifier "sin", that function will be used instead of the predefined MathML function <sin/>.
| bool libsbmlcs.L3ParserSettings.getParseAvogadroCsymbol | ( | ) |
Indicates the current behavior set for handling avogadro for SBML Level 3.
SBML Level 3 defines a symbol for representing the value of Avogadro's constant, but it is not defined in SBML Level 2. As a result, the text-string formula parser must behave differently depending on which SBML Level is being targeted. For Level 3 documents, it can interpret instances of avogadro in the input as a reference to the MathML csymbol for Avogadro's constant defined in the SBML Level 3 specification. For Level 2, it must treat avogadro as just another plain symbol.
This method returns the current setting of the avogadro-handling behavior in this L3ParserSettings object. The possible values are as follows:
true): tells the parser to translate the string avogadro (in any capitalization) into an AST node of type AST_NAME_AVOGADRO. false): tells the parser to translate the string avogadro into an AST of type AST_NAME. | bool libsbmlcs.L3ParserSettings.getParseCollapseMinus | ( | ) |
Indicates the current behavior set for handling multiple unary minuses in formulas.
This setting affects two behaviors. First, pairs of multiple unary minuses in a row (e.g., "- -3") can be collapsed and ignored in the input, or the multiple minuses can be preserved in the AST node tree that is generated by the parser. Second, minus signs in front of numbers can be collapsed into the number node itself; for example, a "- 4.1" can be turned into a single ASTNode of type AST_REAL with a value of -4.1, or it can be turned into a node of type AST_MINUS having a child node of type AST_REAL.
true): collapse unary minuses where possible. false): do not collapse unary minuses, and instead translate each one into an AST node of type AST_MINUS. | bool libsbmlcs.L3ParserSettings.getParseL3v2Functions | ( | ) |
Indicates the current behavior set for handling whether to parse the functions added in L3v2 as that MathML or not.
This setting affects whether the names of functions added in SBML Level 3 Version 2 are parsed as those added MathML functions, or whether they are added as generic functions with those names (to be used in SBML as function definitions).
true): parse the strings 'rateOf', 'implies', 'max', 'min', 'quotient', and 'rem' as AST_FUNCTION_RATE_OF, AST_LOGICAL_IMPLIES, AST_FUNCTION_MAX, AST_FUNCTION_MIN, AST_FUNCTION_QUOTIENT, and AST_FUNCTION_REM, respectively. false): parse the strings 'rateOf', 'implies', 'max', 'min', 'quotient', and 'rem' all as AST_FUNCTION with the appropriate name set. | int libsbmlcs.L3ParserSettings.getParseLog | ( | ) |
Indicates the current behavior set for handling the function log with one argument.
The function log with a single argument ("log(x)") can be parsed as log10(x), ln(x), or treated as an error, as desired. These three possible behaviors are indicated, respectively, by the values L3P_PARSE_LOG_AS_LOG10, L3P_PARSE_LOG_AS_LN, and L3P_PARSE_LOG_AS_ERROR.
| bool libsbmlcs.L3ParserSettings.getParseModuloL3v2 | ( | ) |
Indicates the current behavior set for handling the '' sumbol in mathematical formulas.
This setting affects whether the '' symbol (modulo) is parsed as a piecewise equation that returns the modulo value of the entries on either side of the symbol, or whether it is parsed as the MathML 'rem' function, which was allowed in SBML Level 3 Version 2, but not in previous level/versions. The latter is more succinct, but might not be legal SBML for the desired target SBML document.
true): use the 'rem' MathML function (AST_FUNCTION_REM). false): use a piecewise function (AST_FUNCTION_PIECEWISE) to encode the modulo rule explicitly. | bool libsbmlcs.L3ParserSettings.getParsePackageMath | ( | int | package | ) |
Indicates the current behavior set for handling whether to parse the functions added in the given package as that MathML or not.
This setting affects whether the math added in a given SBML Level 3 package are parsed as those added MathML elements, or whether they are added as generic functions or variables with those names.
true): parse any string defined in a given SBML L3 package as its corresponding ASTType_t. false): parse any string that would have been defined in the given SBML L3 package as AST_FUNCTION or AST_NAME with the appropriate name set. | bool libsbmlcs.L3ParserSettings.getParseUnits | ( | ) |
Indicates the current behavior set for handling units in text-string mathematical formulas.
In SBML Level 2, there is no means of associating a unit of measurement with a pure number in a formula, while SBML Level 3 does define a syntax for this. In Level 3, MathML <cn> elements can have an attribute named units placed in the SBML namespace, which can be used to indicate the units to be associated with the number. The text-string infix formula parser allows units to be placed after raw numbers; they are interpreted as unit identifiers for units defined by the SBML specification or in the containing Model object. Some examples include: "4 mL", "2.01 Hz", "3.1e-6 M", and "(5/8) inches". To produce a valid SBML model, there must either exist a UnitDefinition corresponding to the identifier of the unit, or the unit must be defined in Table 2 of the SBML Level 3 specification.
Since SBML Level 2 does not have the ability to associate units with pure numbers, the value should be expected to be false (L3P_NO_UNITS) when parsing text-string formulas intended for use in SBML Level 2 documents.
true): parse units in the text-string formula. false): treat units in the text-string formula as errors. | void libsbmlcs.L3ParserSettings.setComparisonCaseSensitivity | ( | bool | strcmp | ) |
Sets the parser's behavior with respect to case sensitivity for recognizing predefined symbols.
By default (which is the value L3P_COMPARE_BUILTINS_CASE_INSENSITIVE), the parser compares symbols in a case insensitive manner for built-in functions such as 'sin' and 'piecewise', and for constants such as 'true' and 'avogadro'. Setting this option to L3P_COMPARE_BUILTINS_CASE_SENSITIVE causes the parser to become case sensitive. In that mode, for example, the symbols 'sin' and 'true' will match the built-in values, but the symbols 'SIN', 'Sin', 'True', 'TRUE', and so on, will not.
| strcmp | a boolean indicating whether to be case sensitive (if true) or be case insensitive (if false). |
| void libsbmlcs.L3ParserSettings.setModel | ( | Model | model | ) |
Sets the model reference in this L3ParserSettings object.
When a Model object is provided, identifiers (values of type SId) from that model are used in preference to pre-defined MathML symbol definitions. More precisely, the Model entities whose identifiers will shadow identical symbols in the mathematical formula are: Species, Compartment, Parameter, Reaction, and SpeciesReference. For instance, if the parser is given a Model containing a Species with the identifier "pi", and the formula to be parsed is "3*pi", the MathML produced will contain the construct <ci> pi </ci> instead of the construct <pi/>. Similarly, when a Model object is provided, SId values of user-defined functions present in the Model will be used preferentially over pre-defined MathML functions. For example, if the passed-in Model contains a FunctionDefinition with the identifier "sin", that function will be used instead of the predefined MathML function <sin/>.
| model | a Model object to be used for disambiguating identifiers. |
| void libsbmlcs.L3ParserSettings.setParseAvogadroCsymbol | ( | bool | l2only | ) |
Sets the parser's behavior in handling the symbol avogadro in mathematical formulas.
SBML Level 3 defines a symbol for representing the value of Avogadro's constant, but it is not defined in SBML Level 2. As a result, the text-string formula parser must behave differently depending on which SBML Level is being targeted. For Level 3 documents, it can interpret instances of avogadro in the input as a reference to the MathML csymbol for Avogadro's constant defined in the SBML Level 3 specification. For Level 2, it must treat avogadro as just another plain symbol.
This method allows callers to set the avogadro-handling behavior in this L3ParserSettings object. The possible values of l2only are as follows:
true): tells the parser to translate the string avogadro (in any capitalization) into an AST node of type AST_NAME_AVOGADRO. false): tells the parser to translate the string avogadro into an AST of type AST_NAME. Since SBML Level 2 does not define a symbol for Avogadro's constant, the value should be set to L3P_AVOGADRO_IS_NAME when parsing text-string formulas intended for use in SBML Level 2 documents.
| l2only | a boolean value indicating how the string avogadro should be treated when encountered in a formula. This will be one of the values L3P_AVOGADRO_IS_CSYMBOL or L3P_AVOGADRO_IS_NAME. |
| void libsbmlcs.L3ParserSettings.setParseCollapseMinus | ( | bool | collapseminus | ) |
Sets the behavior for handling unary minuses appearing in mathematical formulas.
This setting affects two behaviors. First, pairs of multiple unary minuses in a row (e.g., "- -3") can be collapsed and ignored in the input, or the multiple minuses can be preserved in the AST node tree that is generated by the parser. Second, minus signs in front of numbers can be collapsed into the number node itself; for example, a "- 4.1" can be turned into a single ASTNode of type AST_REAL with a value of -4.1, or it can be turned into a node of type AST_MINUS having a child node of type AST_REAL.
This method lets you tell the parser which behavior to use—either collapse minuses or always preserve them. The two possibilities are represented using the following constants:
true): collapse unary minuses where possible. false): do not collapse unary minuses, and instead translate each one into an AST node of type AST_MINUS. | collapseminus | a boolean value (one of the constants L3P_COLLAPSE_UNARY_MINUS or L3P_EXPAND_UNARY_MINUS) indicating how unary minus signs in the input should be handled. |
| void libsbmlcs.L3ParserSettings.setParseL3v2Functions | ( | bool | l3v2functions | ) |
Sets the behavior for handling functions added in SBML L3v2.
This setting affects whether the names of functions added in SBML Level 3 Version 2 are parsed as those added MathML functions, or whether they are added as generic functions with those names (to be used in SBML as function definitions).
This method lets you tell the parser which behavior to use—either to parse the functions added in L3v2 as their built-in counterparts, or as generic functions with that name (to be defined by SBML as function definitions). The two possibilities are represented using the following constants:
true): parse the strings 'rateOf', 'implies', 'max', 'min', 'quotient', and 'rem' as AST_FUNCTION_RATE_OF, AST_LOGICAL_IMPLIES, AST_FUNCTION_MAX, AST_FUNCTION_MIN, AST_FUNCTION_QUOTIENT, and AST_FUNCTION_REM, respectively. false): parse the strings 'rateOf', 'implies', 'max', 'min', 'quotient', and 'rem' all as AST_FUNCTION with the appropriate name set. | l3v2functions | a boolean value (one of the constants L3P_PARSE_L3V2_FUNCTIONS_DIRECTLY or L3P_PARSE_L3V2_FUNCTIONS_AS_GENERIC) indicating how to interpret those function names. |
| void libsbmlcs.L3ParserSettings.setParseLog | ( | int | type | ) |
Sets the behavior for handling log in mathematical formulas.
The function log with a single argument ("log(x)") can be parsed as log10(x), ln(x), or treated as an error. These three behaviors are set, respectively, by using the value L3P_PARSE_LOG_AS_LOG10, L3P_PARSE_LOG_AS_LN, or L3P_PARSE_LOG_AS_ERROR for the type parameter.
| type | a constant, one of following three possibilities: |
| void libsbmlcs.L3ParserSettings.setParseModuloL3v2 | ( | bool | modulol3v2 | ) |
Sets the behavior for handling the '' sumbol in mathematical formulas.
This setting affects whether the '' symbol (modulo) is parsed as a piecewise equation that returns the modulo value of the entries on either side of the symbol, or whether it is parsed as the MathML 'rem' function, which was allowed in SBML Level 3 Version 2, but not in previous level/versions. The latter is more succinct, but might not be legal SBML for the desired target SBML document.
This method lets you tell the parser which behavior to use—either parse '' as the 'rem' function or as a piecewise function with the same interpretation. The two possibilities are represented using the following constants:
true): use the 'rem' MathML function (AST_FUNCTION_REM). false): use a piecewise function (AST_FUNCTION_PIECEWISE) to encode the modulo rule explicitly. | modulol3v2 | a boolean value (one of the constants L3P_MODULO_IS_PIECEWISE or L3P_MODULO_IS_REM) indicating how the '' symbol in the input should be handled. |
| void libsbmlcs.L3ParserSettings.setParsePackageMath | ( | int | package, |
| bool | parsepackage | ||
| ) |
Sets the behavior for handling functions added in SBML packages.
This setting affects whether the math added in a given SBML Level 3 package are parsed as those added MathML elements, or whether they are added as generic functions or variables with those names.
This method lets you tell the parser which behavior to use—either to parse the functions added in a given package as their built-in counterparts, or as generic functions with that name (to be defined by SBML as function definitions). The two possibilities are represented using the following constants:
true): parse any string defined in a given SBML L3 package as its corresponding ASTType_t. false): parse any string that would have been defined in the given SBML L3 package as AST_FUNCTION or AST_NAME with the appropriate name set. | package | a boolean value (one of the constants L3P_PARSE_L3V2_FUNCTIONS_DIRECTLY or L3P_PARSE_L3V2_FUNCTIONS_AS_GENERIC) indicating how to interpret those function names. |
| parsepackage | a boolean |
| void libsbmlcs.L3ParserSettings.setParseUnits | ( | bool | units | ) |
Sets the parser's behavior in handling units associated with numbers in a mathematical formula.
In SBML Level 2, there is no means of associating a unit of measurement with a pure number in a formula, while SBML Level 3 does define a syntax for this. In Level 3, MathML <cn> elements can have an attribute named units placed in the SBML namespace, which can be used to indicate the units to be associated with the number. The text-string infix formula parser allows units to be placed after raw numbers; they are interpreted as unit identifiers for units defined by the SBML specification or in the containing Model object. Some examples include: "4 mL", "2.01 Hz", "3.1e-6 M", and "(5/8) inches". To produce a valid SBML model, there must either exist a UnitDefinition corresponding to the identifier of the unit, or the unit must be defined in Table 2 of the SBML Level 3 specification.
This method sets the formula parser's behavior with respect to units.
| units | a boolean indicating whether to parse units. The possible values are as follows: |
true): parse units in the text-string formula. false): treat units in the text-string formula as errors. | void libsbmlcs.L3ParserSettings.unsetModel | ( | ) |
Unsets the Model reference in this L3ParserSettings object.
The effect of calling this method is to set the stored model value to null.
