Method Detail- 
sendMessagepublic 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:
- sendMessagein interface- ChannelInterceptor
- Overrides:
- sendMessagein class- ChannelInterceptorBase
- Parameters:
- destination- Member[] - the destination for this message
- msg- ChannelMessage - the message to be sent
- payload- InterceptorPayload - the payload, carrying an error handler and future useful data, can be null
- Throws:
- ChannelException- if a serialization error happens.
- See Also:
- ErrorHandler,- InterceptorPayload
