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.

Constructor Detail

ForwardingSortedSet

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

Constructs a forwarding sorted set that forwards to the provided delegate.

Method Detail

delegate

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

Description copied from class: ForwardingObject

Returns the backing delegate object. This method should be overridden to specify the correct return type. For example:

  @SuppressWarnings("unchecked")
  @Override protected Foo delegate() {
    return (Foo) super.delegate();
  }

This method should always return the same delegate instance that was passed to the constructor.
