Interface MulticastListener

All Known Implementing Classes:

Atomic, IntGroupHandler, Leadercast, MergingLayer, Multicast, TotalOrderLayer

public interface MulticastListener

This interface enables members to receive message delivery notifications. Members implementing this interface must be able to react in a suitable way to the delivery of messages composed either by single objects or an input stream.

Since:

Jgroup 0.7

Method Summary

java.lang.Object	deliverObject(java.lang.Object msg, MemberId sender, int seqNo) Upcall that is invoked by Jgroup to deliver a message msg, corresponding to a single serialized object.
java.lang.Object	deliverStream(java.io.InputStream msg, MemberId sender, int seqNo) Upcall that is invoked by Jgroup to deliver a message msg, corresponding to an input stream from which the message may be read.
java.lang.String	getProtocolName() Returns a string naming the protocol implemented by this multicast listener.

Method Detail

getProtocolName

java.lang.String getProtocolName()

Returns a string naming the protocol implemented by this multicast listener.

deliverStream

java.lang.Object deliverStream(java.io.InputStream msg,
                               MemberId sender,
                               int seqNo)

Parameters:

msg - the input stream from which the message can be read.

sender - the sender of the multicast message

seqNo - the sequence number of this multicast message

Returns:
