Method Detail

getScope

IScope getScope(org.eclipse.emf.ecore.EObject context,
              org.eclipse.emf.ecore.EReference reference)

Returns a scope for the given context. The scope provides access to the compatible visible EObjects for a given reference.

Parameters:

context - the element from which an element shall be referenced. It doesn't need to be the element containing the reference, it is just used to find the most inner scope for given EReference.

reference - the reference for which to get the scope.

Returns:

IScope representing the innermost IScope for the passed context and reference. Note for implementors: The result may not be null. Return IScope.NULLSCOPE instead.
