sendMessage
public void sendMessage(Member[] destination, ChannelMessage msg, InterceptorPayload payload) throws ChannelException
Description copied from interface:ChannelInterceptorThesendMessagemethod 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.- Specified by:
