IdentityMap (The Adobe Experience Manager SDK 2021.10.5977.20211021T153528Z-211000)

java.lang.Object
- java.util.AbstractMap
- - org.apache.commons.collections.map.AbstractHashedMap
  - - org.apache.commons.collections.map.IdentityMap

All Implemented Interfaces:

Serializable, Cloneable, Map, IterableMap
```
@Deprecated(since="2021-04-30")
public class IdentityMap
extends AbstractHashedMap
implements Serializable, Cloneable
```
Deprecated.
Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.

A Map implementation that matches keys and values based on == not equals().
This map will violate the detail of various Map and map view contracts. As a general rule, don't compare this map to other maps.
Note that IdentityMap 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.synchronizedMap(Map). This class may throw exceptions when accessed by concurrent threads without synchronization.

Since:

Commons Collections 3.0
