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

["Christian W. Damus" <cdamus@xxxxxxx>]

Hi, pokojo,

Sorry, yes, I think our examples used a variable name "model" which probably doesn't exist.  In the context of your root model element you could do:

  self.allOwnedElements()->select(oclIsTypeOf(Class))

or, thanks to the getModel() operation defined by MDT UML2 (not specified by UML 2.x, I don't think), in the context of any element you can do:

  getModel().allOwnedElements()->select(oclIsTypeOf(Class))

Note that "ownedElement.allOwnedElements()" will miss any Classes that are directly owned by the context element (the _expression_'s "self") because it iterates only the elements owned by the elements owned by self.

Cheers,

Christian
