public abstract class ForwardingSortedSet<E>
extends ForwardingSet<E>
implements java.util.SortedSet<E>

A sorted set which forwards all its method calls to another sorted set. Subclasses should override one or more methods to modify the behavior of the backing sorted set as desired per the decorator pattern.

Method Detail

delegate

protected abstract java.util.SortedSet<E> delegate()

Description copied from class: ForwardingObject

Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
