Class ReplicatedMapService

java.lang.Object

com.hazelcast.replicatedmap.impl.ReplicatedMapService

All Implemented Interfaces:

EventPublishingService<Object,Object>, ManagedService, MigrationAwareService, RemoteService, SplitBrainHandlerService, StatisticsAwareService

public class ReplicatedMapService
extends Object
implements ManagedService, RemoteService, EventPublishingService<Object,Object>, MigrationAwareService, SplitBrainHandlerService, StatisticsAwareService

This is the main service implementation to handle proxy creation, event publishing, migration, anti-entropy and manages the backing PartitionContainers that actually hold the data
