[news.eclipse.modeling.mdt.ocl] Re: OCL query to find classes

[Timothy Marc <timothymarc@xxxxxxxxxx>]

As suggested in the UML User Group @ google:

Well, both a look into the UML2 spec and the OCL spec might be very
helpful and recommended...

Since StateMachines, UseCases, Components etc. are all subclasses of
UML::Class, you need a more detailed OCL concept like
oclTypeOf(object) and oclKindOf(object). The first one checks, whether
self is exactly the type of the parameter, the latter one checks if self
is conform (a subclass) to the parameter#s type.

good luck from this starting point!
