public Class DualLinkedHashBidiMap<K, V>

extends AbstractDualBidiMap<K, V>
implements Serializable
Class Inheritance
All Implemented Interfaces
java.io.Serializable
Type Parameters
<K>
the type of the keys in the map
<V>
the type of the values in the map
Imports
java.io.IOException, .ObjectInputStream, .ObjectOutputStream, .Serializable, java.util.LinkedHashMap, .Map, org.apache.commons.collections4.BidiMap
Implementation of BidiMap that uses two LinkedHashMap instances.

Two LinkedHashMap instances are used in this class. This provides fast lookups at the expense of storing two sets of map entries and two linked lists.
