@Deprecated(since="2021-04-30") public class TransformedSortedMap extends TransformedMap implements SortedMap
Deprecated.Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.Decorates anotherSortedMap
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
Collections.synchronizedSortedMap(java.util.SortedMap<K, V>)
. This class may throw exceptions when accessed by concurrent threads without synchronization.This class is Serializable from Commons Collections 3.1.
- Since:
- Commons Collections 3.0

Method Detail

decorate
public static SortedMap decorate(SortedMap map, Transformer keyTransformer, Transformer valueTransformer)
Deprecated.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
decorateTransform(java.util.SortedMap, org.apache.commons.collections.Transformer, org.apache.commons.collections.Transformer)
.- Parameters:
map
- the map to decorate, must not be nullkeyTransformer
- the predicate to validate the keys, null means no transformationvalueTransformer
- 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)
Deprecated.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
decorate(java.util.SortedMap, org.apache.commons.collections.Transformer, org.apache.commons.collections.Transformer)
.- Parameters:
map
- the map to decorate, must not be nullkeyTransformer
- the transformer to use for key conversion, null means no transformationvalueTransformer
- the transformer to use for value conversion, null means no transformation- Throws:
IllegalArgumentException
- if map is null- Since:
- Commons Collections 3.2
