|
LRUMap
|
|
------
|
|
|
|
LRUMap has been reimplemented as a subclass of
|
|
SynchronizedHashMap. The new implementation of
|
|
LRUMap should be faster, and it also offers true LRU
|
|
capabilities; now any get(Object) or
|
|
put(Object,Object) from this collection
|
|
promotes the key to the Most Recently Used position.
|
|
|
|
LRUMap 2.0 compatibility changes:
|
|
- LRUMap can no longer be cast to a HashMap.
|
|
- The removeLRU() method now has a different
|
|
signature, and is no longer public. There is
|
|
no direct replacement for this method.
|
|
- "Externalized" LRUMap 1.0 Objects cannot be
|
|
read by LRUMap 2.0.
|
|
|
|
New features:
|
|
- True LRU algorithm.
|
|
- New methods from SequencedHashMap superclass.
|
|
- processRemovedLRU(Object key, Object value) method
|
|
allows subclasses to perform custom actions on
|
|
keys and values that are expunged from the Map.
|
|
|
|
Bugs fixed:
|
|
- calling setMaximumSize(int) will remove excess LRUs
|
|
when the current size of the Map exceeds the new
|
|
maximum size
