Description copied from interface: LibraryOperation

Return the result of evaluating callExp and its arguments upon sourceValue within the environment provided by evaluator. An invalid return may be indicated by throwing an exception, returning Java null, or returning OCL invalid.

This invocation evaluates the arguments as required. Derived implementations may implement short circuit processing to skip redundant evlaution of later arguments.

Invocations may bypass dispatch if a derived LibraryOperation such as LibrarySimpleBinaryOperation makes its internal evaluate signature available for use after a type test and cast.
