public abstract class ForwardingSortedSet<E>
- extends ForwardingSet<E>
- implements 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.

ForwardingSortedSet
protected ForwardingSortedSet(SortedSet<E> delegate)
- Constructs a forwarding sorted set that forwards to the provided delegate.
delegate
protected 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.
