sendMessage
public void sendMessage(Member[] destination,
                        ChannelMessage msg,
                        InterceptorPayload payload)
                 throws ChannelException
- Description copied from interface: ChannelInterceptor
- The sendMessagemethod is called when a message is being sent to one more destinations.
 The interceptor can modify any of the parameters and then pass on the message down the stack by
 invokinggetNext().sendMessage(destination,msg,payload)
 Alternatively the interceptor can stop the message from being sent by not invokinggetNext().sendMessage(destination,msg,payload)
 If the message is to be sent asynchronous the application can be notified of completion and 
 errors by passing in an error handler attached to a payload object.
 The ChannelMessage.getAddress contains Channel.getLocalMember, and can be overwritten 
 to simulate a message sent from another node.
