- 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.Set<E>
,java.util.SortedSet<E>
- Direct Known Subclasses:
TransformedNavigableSet
public class TransformedSortedSet<E> extends TransformedSet<E> implements java.util.SortedSet<E>
Decorates anotherSortedSet
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.
This class is Serializable from Commons Collections 3.1.

transformingSortedSet
public static <E> TransformedSortedSet<E> transformingSortedSet(java.util.SortedSet<E> set, Transformer<? super E,? extends E> transformer)
Factory method to create a transforming sorted set.If there are any elements already in the set being decorated, they are NOT transformed. Contrast this with
transformedSortedSet(SortedSet, 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
SortedSet
- Throws:
java.lang.NullPointerException
- if set or transformer is null- Since:
- 4.0

transformedSortedSet
public static <E> TransformedSortedSet<E> transformedSortedSet(java.util.SortedSet<E> set, Transformer<? super E,? extends E> transformer)
Factory method to create a transforming sorted set that will transform existing contents of the specified sorted set.If there are any elements already in the set being decorated, they will be transformed by this method. Contrast this with
transformingSortedSet(SortedSet, 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
