public interface ADFScope

extends java.util.Map

Since:

release specific (what release of product did this appear in)

Defines an interface for ADFScopes.

This interface defines scope operations that are not supported by the base Map scope interface. These operations include: Scope invalidation, scope lifecycle notifications.

A scope user may invalidate a scope by invoking the invalidate() operation on this interface. After an ADFScope is invalidated the scope's state will be unreachable and all cached references to the invalid ADFScope must be nulled. If a scope is used after it is invalidated it may throw a RuntimeException (InvalidStateException).

A scope client may be notified of invalidation events by using the addScopeListener(ADFScopeListener) to register an invalidation listener.
