Class ASTNodeValue

java.lang.Object

org.simulator.sbml.astnode.ASTNodeValue

Direct Known Subclasses:

CompartmentOrParameterValue, DivideValue, FunctionValue, IntegerValue, LocalParameterValue, MinusValue, NamedValue, PlusValue, PowerValue, ReactionValue, RootFunctionValue, SpeciesReferenceValue, SpeciesValue, TimesValue

public class ASTNodeValue
extends Object

This class can compute and store the interpreted value (double or boolean) of an ASTNode at the current time. A new computation is only done if the time has changed. So the computation is time-efficient.
