Class JGroupsBuffer

java.lang.Object

org.reveno.atp.clustering.core.components.AbstractClusterBuffer

org.reveno.atp.clustering.core.jgroups.JGroupsBuffer

All Implemented Interfaces:

ClusterBuffer, org.reveno.atp.core.api.channel.Buffer

public class JGroupsBuffer
extends AbstractClusterBuffer
implements ClusterBuffer

JGroups implementation of ClusterBuffer. It is intended to be used mainly for test and debug purposes, as it's not very efficient approach in low-latency world.
