Method Detail

createOCLHelper

public static <PK,C,O,P,EL,PM,S,COA,SSA,CT,CLS,E> OCLHelper<C,O,P,CT> createOCLHelper(OCL<PK,C,O,P,EL,PM,S,COA,SSA,CT,CLS,E> ocl)

Creates an OCLHelper for the specified EMF metamodel. The factory creates OCL environments (with the packages, classifiers, states, etc.) from the instances of the metaclasses that mimic OCL/UML classifiers.

The new helper validates the OCL expressions that it parses.

Parameters:

ocl - the metamodel-specific OCL environment

Returns:

the new OCL helper
