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.

Method Summary

void	clearStates()
State	getState(K key)
void	putState(K key, State state)

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.
