Parameters:

problemObject - the object which could have problems.

env - the OCL environment

owner - the type of the operation call source

Obtains the effective result type of the specified operation, which may or may not have parameters type by generic type variables. Many of the OCL Standard Library operations are either generic themselves or defined by generic types, so the return results depend on the argument and source types.

Parameters:

problemObject - the context object on which to report any problem that we may find in computing the result type. Usually this is some abstract or concrete syntax tree node

env - the OCL environment

owner - the owner of the operation (type on which the operation is called)

operation - the operation signature

args - the arguments of the operation call, which are expressions or variables

Returns:

the effective result type of the corresponding operation, or null after reporting a problem if any of the argument types do not correspond to the source type and/or expected parameter types of the operation

Deprecated. Use the getRelationship(Environment, Object, Object) method, instead.

Compare two types. Returns 0 if types are exactly equal, -1 if type1 conforms to type2 (type1 is a subtype of type2) 1 if type2 conforms to type1 (type2 is a subtype of type1). Fails if there is no type conformance.

Parameters:

type1 - a type

type2 - another type

Returns:

the ordering key

Throws:

IllegalArgumentException - if the types are not conformant one way or the other
