Hi,
I am trying to locate a collection of UML class names in another collection of UML classes.
I have reach the following expression:
UML2!"uml::Class".allInstancesFrom('INModel')->select(s | s.hasStereotype('TESTCOMPONENT'))
which provide me with all classes with stereotypes "testcomponent", and it works fine.
I have another module attribute which holds a collection of names that I need to find & extract from previous expression.
Your help to complete this expression is appreciated, and thanks in advance.
Yours,
Mohamed

Thanks Ed Willink,
I'm sorry for my ESL. Yes, it is an ATL command. I studied OCL 3 yrs ago, but I didn't practice it.
Here is my question:
How to locate the existence of an OCL collection in another OCL collection, which represents a UML classes, and point to these UML classes in a new collection if found?
To clarify, lets go through the following ex.:
Suppose we have the following collection
Col1={A, k, L} Note: I have this one.
and we have UML Diagram with the following
UML classes = {A, B, C, K, R} Note: I have this one.
I want to write an OCL/ATL expression to locate the existence of any of the Col1's members among the UML classes, so the result should be
Matched UML classes = {A, K} Note: I need to reach this one.
I hope I clarified my request.
Yours,
Mohamed

I'm afraid that the vagueness of your English makes it difficult to
understand exactly what you want.
I suggest expressing the algorithm clearly and you may then find that it
maps to select/includes/union/... operators.
Your example is clearly not OCL; probably ATL. OCL has no ! or ",
although for historical compatibility OCL allows "" to enclose names,
but that would make "uml::Class" one not two names.

Hi
The union, intersection, -, symmetricDifference, includes, excludes
operations allow you to do a variety of collection operations.

Thanks for your respond.
I have solved the problem
UML2!"uml::Class".allInstancesFrom('IN')->select(s | s.hasStereotype('TESTCOMPONENT'))->collect(sn | sn.name.toUpper())->select(t| thisModule.contextSUT.includes(t));
and the contextSUT collection must be in uppercase
My best regards,
Mohamed
