| TransformedSortedMap | | public class TransformedSortedMap extends TransformedMap implements SortedMap(Code) | | Decorates another SortedMap to transform objects that are added.
The Map put methods and Map.Entry setValue method 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.
Note that TransformedSortedMap is not synchronized and is not thread-safe.
If you wish to use this map from multiple threads concurrently, you must use
appropriate synchronization. The simplest approach is to wrap this map
using
java.util.Collections.synchronizedSortedMap . This class may throw
exceptions when accessed by concurrent threads without synchronization.
This class is Serializable from Commons Collections 3.1.

| TransformedSortedMap | | protected TransformedSortedMap(SortedMap map, Transformer keyTransformer, Transformer valueTransformer)(Code) | | Constructor that wraps (not copies).
If there are any elements already in the collection being decorated, they
are NOT transformed.
Parameters:
map - the map to decorate, must not be null
Parameters:
keyTransformer - the predicate to validate the keys, null means no transformation
Parameters:
valueTransformer - the predicate to validate to values, null means no transformation
throws:
IllegalArgumentException - if the map is null |
| decorate | | public static SortedMap decorate(SortedMap map, Transformer keyTransformer, Transformer valueTransformer)(Code) | | Factory method to create a transforming sorted map.
If there are any elements already in the map being decorated, they
are NOT transformed.
Constrast this with
TransformedSortedMap.decorateTransform .
Parameters:
map - the map to decorate, must not be null
Parameters:
keyTransformer - the predicate to validate the keys, null means no transformation
Parameters:
valueTransformer - the predicate to validate to values, null means no transformation
throws:
IllegalArgumentException - if the map is null |
| decorateTransform | | public static SortedMap decorateTransform(SortedMap map, Transformer keyTransformer, Transformer valueTransformer)(Code) | | Factory method to create a transforming sorted map that will transform
existing contents of the specified map.
If there are any elements already in the map being decorated, they
will be transformed by this method.
Constrast this with
TransformedSortedMap.decorate .
Parameters:
map - the map to decorate, must not be null
Parameters:
keyTransformer - the transformer to use for key conversion, null means no transformation
Parameters:
valueTransformer - the transformer to use for value conversion, null means no transformation
throws:
IllegalArgumentException - if map is null
