Adding an operation that returns a set in an implementation class throws an exception.

[Omar Alam]

I was trying to add the operation keySet() in the HashMap implementation class, in the Association concern (see attached figure). The operation keySet() is added but its return type (which is a Set) is missing. The tool throws the following exception:

ca.mcgill.cs.sel.ram.impl.OperationImpl@6b584128 (name: keySet) (abstract: false, visibility: public, static: false, partial: false, operationType: Normal) : returnTypeDefined (if self.returnType.oclIsInvalid().or(self.returnType.oclIsUndefined()) then false else let sv : ram::StructuralView[?] = self.oclContainer().oclAsType(ram::Classifier).oclContainer().oclAsType(ram::StructuralView) in sv.types->includes(self.returnType).or(sv.oclContainer().oclAsType(ram::Aspect).containsTypeInEnumsOrClasses(self.returnType)) endif)
'NavigableObject' rather than 'OclVoid' value required

[Matthias Schoettle]

The reason is that Set<Key> is imported and then it tries to find Set<Key> (in your case), but it cannot be found, because types of type Class are ignored when determining the complete class name including generics (in RamModelUtils.getClassNameWithGenerics(...).

[Matthias Schoettle]

Resolves #263: Adds handling of a RAM class so that its name is added to the overall class name (if a Class is the generic type). This ignores the actual textual representation (i.e., partial is omitted) of the class, but it is done uniformly for this case.
