Method Detail

add

V add(K key,
      V value,
      long now)

addTransient

void addTransient(K key,
                  long now)

addBackup

loadAll

Map loadAll(Collection keys)

removeAll

void removeAll(Collection keys)

Removes keys from map store. It also handles Data to object conversions of keys.

Parameters:

keys - to be removed.

loadable

boolean loadable(K key,
                 long lastUpdateTime,
                 long now)

notFinishedOperationsCount

int notFinishedOperationsCount()

isPostProcessingMapStore

boolean isPostProcessingMapStore()

flush

Collection<Data> flush()

Flushes all keys in this map-store.

Returns:

flushed Data keys list.

flush

V flush(K key,
        V value,
        long now,
        boolean backup)

Flushes the supplied key to the map-store.

Parameters:

key - key to be flushed

value - value to be flushed

now - now in millis

backup - true calling this method for backup partition, false for owner partition.

Returns:

flushed value.
