Field Summary

protected int	compartmentIndex The index of the compartment of the species (if applicable)
protected boolean	hasOnlySubstanceUnits The hasOnlySubstanceUnits attribute of the species (if applicable)
protected boolean	hasZeroSpatialDimensions This flag is true if the variable is a species and its compartment has no spatial dimensions
protected int	index The index of the variable in the Y vector of the value holder
protected boolean	isSetInitialAmount The isSetInitialAmount attribute of the species (if applicable)
protected boolean	isSetInitialConcentration The isSetInitialConcentration attribute of the species (if applicable)
protected boolean	isSpecies Flag that is true if the variable is referring to a species, otherwise false
protected ASTNodeValue	nodeObject Object that refers to the math of the rule
protected double	value The calculated value of the rul
protected SBMLValueHolder	valueHolder The value holder that stores the current simulation results

Constructor Summary

RuleValue(ASTNodeValue nodeObject, int index)

RuleValue(ASTNodeValue nodeObject, int index, Species sp, int compartmentIndex, boolean hasZeroSpatialDimensions, SBMLValueHolder valueHolder)
Constructor for rules that refer to a species.

Method Summary

int	getIndex() Returns the index of the variable in the Y vector of the value holder.
double	getValue() Returns the value of the rule.
protected double	processAssignmentVariable(double time) Calculates the math of the rule and returns the new value of the variable.
