Class IncomingPacketsLastAck

java.lang.Object

com.avaje.ebeaninternal.server.cluster.mcast.IncomingPacketsLastAck

public class IncomingPacketsLastAck
extends Object

For this node this holds the ACK gotAllPoint for each member in the cluster.

As we receive messages from other members of the cluster periodically we need to send them ACK messages to say we got all the packets up to the gotAllPoint.

Thread Safety note: Object only used by McastClusterBroadcast Manager thread. So Single Threaded access.
