## org.apache.catalina.cluster
Class MulticastReceiver

    java.lang.Object
      org.apache.catalina.cluster.ClusterSessionBase
          org.apache.catalina.cluster.MulticastReceiver

All Implemented Interfaces:
  ClusterReceiver, java.lang.Runnable

public final class MulticastReceiver
extends ClusterSessionBase
implements ClusterReceiver

This class is responsible for checking for incoming multicast data and determine if the data belongs to us and if so push it onto an internal stack and let it be picked up when needed.
