Hi, Victor,
Are you talking about an Ecore package or a UML package?
If the former, try evaluating
self.eClassifiers->select(instanceof(EClass))
on your package. If the latter,
self.ownedType->select(instanceof(Class))

Hi, Victor,
I'm not sure that I understand fully. I think you want to search for
packages by qualified name? Also, allOwnedElements is recursive, so it
will also obtain classes that maybe you don't want:
- classes nested in other classifiers of the package
- classes in nested packages
How about this?
context NamedElement
def: getAllClassesOfPackage(qname : String) : Set(Class) =
Package.allInstances()->any(qualifiedName = qname).ownedType->
iterate(t : Type; c : Set(Class) = Set{} |
if t.oclIsKindOf(Class)
then c->including(t.oclAsType(Class))
else c
endif)
Note that OCL 2.0 doesn't provide a means to cast collection types (this
will be fixed by OCL 2.1).
If you're looking for a stereotype by name, then just change the "if"
condition using the Element::getAppliedStereotype(...) operation from
the Eclipse UML2 implementation
context NamedElement
def: getAllClassesOfPackage(qname : String, stereotype: String) :
Set(Class) =
Package.allInstances()->any(qualifiedName = qname).ownedType->
iterate(t : Type; c : Set(Class) = Set{} |
if not t.getAppliedStereotype(stereotype).oclIsUndefined()
then c->including(t.oclAsType(Class))
else c
endif)
Assuming that the stereotype extends the Class metaclass, so that we are
implicitly checking that the type is a class.
