public class TransformedNavigableSet<E> extends TransformedSortedSet<E> implements NavigableSet<E>
Decorates anotherNavigableSet
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.

transformingNavigableSet
public static <E> TransformedNavigableSet<E> transformingNavigableSet(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 nulltransformer
- the transformer to use for conversion, must not be null- Returns:
- a new transformed
NavigableSet
- Throws:
NullPointerException
- if set or transformer is null
-
transformedNavigableSet
public static <E> TransformedNavigableSet<E> transformedNavigableSet(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:

- the element type- Parameters:
set
- the set to decorate, must not be nulltransformer
- the transformer to use for conversion, must not be null- Returns:
- a new transformed
