- All Implemented Interfaces:
- Serializable, Map<K,V>, BidiMap<K,V>, Get<K,V>, IterableGet<K,V>, IterableMap<K,V>, Put<K,V>
public class DualLinkedHashBidiMap<K,V>
- extends AbstractDualBidiMap<K,V>
- implements Serializable
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.
