Map.
|
| CompositeMap
Decorates a map of other maps to provide a single unified view.
|
| CompositeMap.MapMutator
This interface allows definition for all of the indeterminate mutators in a CompositeMap, as well as providing a hook for callbacks on key collisions.
|
| DefaultedMap
Decorates another
Map returning a default value if the map does not contain the requested key.
|
| EntrySetToMapIteratorAdapter
Adapts a Map entrySet to the MapIterator interface.
|

SortedMap to create objects in the map on demand.
|
| LinkedMap
A
Map implementation that maintains the order of the entries.
|
| ListOrderedMap
Decorates a
Map to ensure that the order of addition is retained using a
List to maintain order.
|
| LRUMap
A
Map implementation with a fixed maximum size which removes the least recently used entry if an entry is added when full.
|
| MultiKeyMap
A
Map implementation that uses multiple keys to map the value.
|
| MultiValueMap
