Method Detail

evaluate

public Value evaluate(ValueFactory valueFactory,
                      Value sourceVal)
               throws InvalidValueException

Description copied from interface: LibraryUnaryOperation

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

sourceVal - the argument

Returns:

the evaluated value

Throws:

InvalidValueException

evaluateReal

protected Value evaluateReal(RealValue left)
                      throws InvalidValueException

Throws:

InvalidValueException

evaluateInteger

protected Value evaluateInteger(IntegerValue left)
                         throws InvalidValueException

Throws:

InvalidValueException

evaluateUnlimited

protected Value evaluateUnlimited(java.lang.Object left)
                           throws InvalidValueException

Throws:

InvalidValueException

evaluateNumeric

protected <T extends NumericValue> Value evaluateNumeric(T left)
                         throws InvalidValueException

Return the result of evaluating the operation on left. A null return or an exception may be used for invalid.

Throws:

InvalidValueException
