    - #### sendMessage

          public void sendMessage(Member[] destination,
                         ChannelMessage msg,
                         InterceptorPayload payload)
                           throws ChannelException

      Description copied from interface: `ChannelInterceptor`
      The `sendMessage` method 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 invoking `getNext().sendMessage(destination,msg,payload)`
      Alternatively the interceptor can stop the message from being sent by not invoking `getNext().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:
        `sendMessage` in interface `ChannelInterceptor`
      Overrides:
        `sendMessage` in 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.

        `ErrorHandler`, `InterceptorPayload`

          public void messageReceived(ChannelMessage msg)

      Description copied from interface: `ChannelInterceptor`
