evaluate

public BooleanValue evaluate(EvaluationVisitor evaluationVisitor,
                             Value sourceVal,
                             OperationCallExp operationCall)
                      throws InvalidValueException

Description copied from interface: LibraryOperation

Return the result of evaluating operationCall upon sourceVal within the environment provided by EvaluationVisitor. An invalid return may be indicated by throwing an exception returning Java null or OCL invalid.

Specified by:

evaluate in interface LibraryOperation

Overrides:

evaluate in class AbstractBinaryOperation

Parameters:

evaluationVisitor - the evaluation context

sourceVal - the source operand for the operation

operationCall - the operation and additional arguments

Returns:

the evaluated value

Throws:

InvalidValueException

evaluate

public BooleanValue evaluate(ValueFactory valueFactory,
                             Value left,
                             Value right)
                      throws InvalidValueException

Description copied from interface: LibraryBinaryOperation

Return the result of evaluating the operation on left and right arguments. An invalid return may be indicated by throwing an exception returning Java null or OCL invalid.

left - left argument

right - argument

Returns:

the evaluated value

Throws:

InvalidValueException
