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.

Method Detail

delegate

protected abstract 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.

Specified by:
delegate in class ForwardingSet<E>

comparator

public Comparator<? super E> comparator()
Specified by:
comparator in interface SortedSet<E>

first

public E first()
Specified by:
first in interface SortedSet<E>

headSet

public SortedSet<E> headSet(E toElement)
Specified by:
headSet in interface SortedSet<E>

last

public E last()
Specified by:
last in interface SortedSet<E>

subSet

public SortedSet<E> subSet(E fromElement,
                           E toElement)
Specified by:
subSet in interface SortedSet<E>

tailSet

public SortedSet<E> tailSet(E fromElement)
Specified by:
tailSet in interface SortedSet<E>
