Interface StatefulMap<K,V>

All Superinterfaces:

Map<K,V>

All Known Implementing Classes:

StatefulHashMap

public interface StatefulMap<K,V>
extends Map<K,V>

StatefulMap extends the Map interface to keep track of the persistency states of individual elements in the Map.

Nested Class Summary

Nested classes/interfaces inherited from interface java.util.Map

Map.Entry<K,V>

Method Summary

void	clearStates()
State	getState(K key)
void	putState(K key, State state)
void	reuse() Reuse will clear the map completely with states.
Map<K,State>	states()

Method Detail

getState

State getState(K key)

putState

void putState(K key,
              State state)

states

Map<K,State> states()

clearStates

void clearStates()

reuse

void reuse()

Reuse will clear the map completely with states. This is different from Map.clear() in that the latter only sets entries to deleted.
