public abstract class DelegatingQueryResourcesContext
extends Object
implements IStoreAccessor.QueryResourcesContext
Wrapper base for query-resource contexts that forwards query scope and result collection to a delegate. Subclasses
can adapt selected query behavior while retaining the delegate's branch point, folder, and result handling.
