| ReplicatedMap | | public class ReplicatedMap extends AbstractReplicatedMap implements RpcCallback,ChannelListener,MembershipListener(Code) | | All-to-all replication for a hash map implementation. Each node in the cluster will carry an identical
copy of the map.
This map implementation doesn't have a background thread running to replicate changes.
If you do have changes without invoking put/remove then you need to invoke one of the following methods:
replicate(Object,boolean) - replicates only the object that belongs to the keyreplicate(boolean) - Scans the entire map for changes and replicates data
the boolean value in the replicate method used to decide
whether to only replicate objects that implement the ReplicatedMapEntry interface
or to replicate all objects. If an object doesn't implement the ReplicatedMapEntry interface
each time the object gets replicated the entire object gets serialized, hence a call to replicate(true)
will replicate all objects in this map that are using this node as primary.
REMBER TO CALL breakdown() or finalize() when you are done with the map to
avoid memory leaks.
