Class TransformedSortedBag<E>
java.lang.Object
org.apache.commons.collections4.collection.AbstractCollectionDecorator<E>
org.apache.commons.collections4.collection.TransformedCollection<E>
org.apache.commons.collections4.bag.TransformedBag<E>
org.apache.commons.collections4.bag.TransformedSortedBag<E>
- Type Parameters:
- E- the type of elements in this bag
- All Implemented Interfaces:
- Serializable,- Iterable<E>,- Collection<E>,- Bag<E>,- SortedBag<E>
Decorates another 
SortedBag 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.

Constructor Details- 
TransformedSortedBagConstructor that wraps (not copies).If there are any elements already in the bag being decorated, they are NOT transformed. - Parameters:
- bag- the bag to decorate, must not be null
- transformer- the transformer to use for conversion, must not be null
- Throws:
- NullPointerException- if bag or transformer is null

Method Details- 
transformedSortedBagpublic static <E> TransformedSortedBag<E> transformedSortedBag(SortedBag<E> bag, Transformer<? super E, ? extends E> transformer) Factory method to create a transforming sorted bag that will transform existing contents of the specified sorted bag.If there are any elements already in the bag being decorated, they will be transformed by this method. Contrast this with transformingSortedBag(SortedBag, Transformer).- Type Parameters:
- E- the type of the elements in the bag
- Parameters:
- bag- the bag to decorate, must not be null
- transformer- the transformer to use for conversion, must not be null
- Returns:
- a new transformed SortedBag
- Throws:
- NullPointerException- if bag or transformer is null
- Since:
- 4.0
