Interface IDelegatingScopeProvider

All Superinterfaces:

IScopeProvider

All Known Implementing Classes:

AbstractDeclarativeScopeProvider, DelegatingScopeProvider

public interface IDelegatingScopeProvider
extends IScopeProvider

A delegating scope provider marks an implementation, that handles only a couple of cases but will use another IScopeProvider to compute its parent scope or that takes care of other cases. It is used to provide (recursive) access to the implementation, that will finally delegate to the global scope. This is necessary to allow wrapping of global scopes to keep track of imported names.

2.1
