evictAll

public void evictAll()

Description copied from interface: IMap

Evicts all keys from this map except the locked ones.

If a MapStore is defined for this map, deleteAll is not called by this method. If you do want to deleteAll to be called use the IMap.clear() method.

The EVICT_ALL event is fired for any registered listeners. See MapEvictedListener.mapEvicted(MapEvent) .

Specified by:

evictAll in interface IMap<K,V>

Overrides:

evictAll in class ClientMapProxy<K,V>

See Also:

IMap.clear()

loadAll

public void loadAll(boolean replaceExistingValues)

Description copied from interface: IMap

Loads all keys into the store. This is a batch load operation so that an implementation can optimize the multiple loads.

Specified by:

loadAll in interface IMap<K,V>

Overrides:

loadAll in class ClientMapProxy<K,V>

Parameters:

replaceExistingValues - when true, existing values in the Map will be replaced by those loaded from the MapLoader void loadAll(boolean replaceExistingValues));

loadAllInternal

protected void loadAllInternal(boolean replaceExistingValues,
                               Collection<?> keysParameter)

Overrides:

loadAllInternal in class ClientMapProxy<K,V>

protected void getAllInternal(Set<K> keys,
                              Map<Integer,List<Data>> partitionToKeyData,
                              List<Object> resultingKeyValuePairs)

Overrides:

getAllInternal in class ClientMapProxy<K,V>

getLocalMapStats

public LocalMapStats getLocalMapStats()

Description copied from interface: IMap

Returns LocalMapStats for this map.

LocalMapStats are the statistics for the local portion of this distributed map and contains information such as ownedEntryCount backupEntryCount, lastUpdateTime, lockedEntryCount.

Since this stats are only for the local portion of this map, if you need the cluster-wide MapStats then you need to get the LocalMapStats from all members of the cluster and combine them.

Specified by:

getLocalMapStats in interface IMap<K,V>

Overrides:

getLocalMapStats in class ClientMapProxy<K,V>

Returns:

this map's local statistics

                              Map<Integer,List<Map.Entry<Data,Data>>> entryMap)

Overrides:

putAllInternal in class ClientMapProxy<K,V>

clear

public void clear()

Description copied from interface: IMap

Clears the map and invokes MapStore.deleteAll(java.util.Collection<K>)deleteAll on MapStore which, if connected to a database, will delete the records from that database.

The MAP_CLEARED event is fired for any registered listeners. See MapClearedListener.mapCleared(MapEvent).

To clear a map without calling MapStore.deleteAll(java.util.Collection<K>), use IMap.evictAll().

Specified by:

clear in interface IMap<K,V>

Specified by:

clear in interface Map<K,V>

Overrides:

clear in class ClientMapProxy<K,V>
