Hello.
When evaluating OCL operations programmatically, I would like to cast UML elements as EObjects, in order to call operations such as eContainingFeature. The code I was formerly using, which was based on the classic API, was doing the following :
OCl ocl = ...
ParsingOptions.setOption(ocl.getEnvironment(), ParsingOptions.implicitRootClass(ocl.getEnvironment()), EcorePackage.Literals.EOBJECT);
However the org.eclipse.ocl.examples.pivot.options.ParsingOptions#IMPLICIT_ROOT_CLASS is marked as deprecated. Is there a way / a workaround to allow casting into the EObject type ? Currently, when evaluating such a cast, I have the following error message : Incompatible source type: 'UML::Package' for oclAsType(ecore::EObject)
Regards,
Olivier

Hi
I think that most of the EObject use cases are addressed without the
cast. So oclContainer() for eContainer(), oclType() for eClass().
Stereotype navigation now has a type safe syntax.
The Pivot OCL supports OMG OCL not EOCL, so UML::Package is not an
EObject specification wise.
