| TimeBoundHashMap | | public class TimeBoundHashMap extends HashMap (Code) | | TimeBoundHashMap is a HashMap sub class that purges entries using
a last accessed time mechanism.
The time out control is done when using the accessor methods of the Map,
no extra Thread is used for it.
This class is not Thread-safe, if a TimeBoundHashMap instance is to be
used in a multithreaded fashion it should be wrapped with a synchronized
Map (see the Collections.synchronizedMap() method).
