Type Parameters:

E - the type of the elements in this set

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.NavigableSet<E>, java.util.Set<E>, java.util.SortedSet<E>

public class TransformedNavigableSet<E>
extends TransformedSortedSet<E>
implements java.util.NavigableSet<E>

Decorates another NavigableSet to transform objects that are added.

The add methods are affected by this class. Thus objects must be removed or searched for using their transformed form. For example, if the transformation converts Strings to Integers, you must use the Integer form to remove objects.

Method Detail

transformingNavigableSet

public static <E> TransformedNavigableSet<E> transformingNavigableSet(java.util.NavigableSet<E> set,
                                                                      Transformer<? super E,? extends E> transformer)

Factory method to create a transforming navigable set.

If there are any elements already in the set being decorated, they are NOT transformed. Contrast this with transformedNavigableSet(NavigableSet, Transformer).

Type Parameters:

E - the element type

Parameters:

set - the set to decorate, must not be null

transformer - the transformer to use for conversion, must not be null

Returns:

a new transformed NavigableSet

Throws:

java.lang.NullPointerException - if set or transformer is null

transformedNavigableSet

public static <E> TransformedNavigableSet<E> transformedNavigableSet(java.util.NavigableSet<E> set,
                                                                     Transformer<? super E,? extends E> transformer)

Factory method to create a transforming navigable set that will transform existing contents of the specified navigable set.

If there are any elements already in the set being decorated, they will be transformed by this method. Contrast this with transformingNavigableSet(NavigableSet, Transformer).

Type Parameters:

E - the element type

Parameters:

set - the set to decorate, must not be null

transformer - the transformer to use for conversion, must not be null

Returns:

a new transformed NavigableSet

Throws:

java.lang.NullPointerException - if set or transformer is null
