Description Sven Efftinge CLA 2010-10-13 08:28:11 EDT 
In order to query and filter the contents of each scope taking the shadowing into account, we should allow to pass a filter predicate when asking for IEObjectDescription.
Comment 1 Jan Koehnlein CLA 2010-10-14 05:44:29 EDT 
Summarizing our discussion results:
The methods of the IScope interface are a cross product of filtering aspects (by EObject, by name, by predicate) and result type (list or single element). We should simplify that by extracting the filtering aspect into a separate interface, something like

interface IScope {
  Iterable<IEObjectDescriptor> getElements(IScopeFilter filter);
  IEObjectDescriptor getFirstElement(IScopeFilter filter);
}

interface IScopeFilter {
  static class ByName implements IScopeFilter {..} 
  static class ByEObject implements IScopeFilter {..}
  static class ByPredicate implements IScopeFilter {..}
}

For backward compatibility with existing clients, we should consider introducing a compatibility layer.
Comment 2 Sven Efftinge CLA 2010-11-22 07:38:20 EST 
I also changed IResourceDescription and IContainer accordingly.
