DualHashBidiMap (The Adobe AEM Quickstart and Web Application. 6.6.0)

java.lang.Object
- org.apache.commons.collections.bidimap.AbstractDualBidiMap
- - org.apache.commons.collections.bidimap.DualHashBidiMap

All Implemented Interfaces:

java.io.Serializable, java.util.Map, BidiMap, IterableMap
```
public class DualHashBidiMap
extends AbstractDualBidiMap
implements java.io.Serializable
```
Implementation of BidiMap that uses two HashMap instances.
Two HashMap instances are used in this class. This provides fast lookups at the expense of storing two sets of map entries. Commons Collections would welcome the addition of a direct hash-based implementation of the BidiMap interface.
NOTE: From Commons Collections 3.1, all subclasses will use HashMap and the flawed createMap method is ignored.

Since:

Commons Collections 3.0
