Class ForwardingSortedSet<E>

java.lang.Object

org.glassfish.jersey.internal.guava.ForwardingCollection<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>, Set<E>, SortedSet<E>

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.

Warning: The methods of ForwardingSortedSet forward indiscriminately to the methods of the delegate. For example, overriding ForwardingCollection.add(E) alone will not change the behavior of ForwardingCollection.addAll(java.util.Collection<? extends E>), which can lead to unexpected behavior. In this case, you should override addAll as well, either providing your own implementation, or delegating to the provided standardAddAll method.

Each of the standard methods, where appropriate, uses the set's comparator (or the natural ordering of the elements, if there is no comparator) to test element equality. As a result, if the comparator is not consistent with equals, some of the standard implementations may violate the Set contract.

The standard methods and the collection views they return are not guaranteed to be thread-safe, even when all of the methods that they depend on are thread-safe.

Method Detail

delegate

protected abstract SortedSet<E> delegate()

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>

toString

public String toString()

Returns the string representation generated by the delegate's toString method.

Overrides:
