Method Detail

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
See Also:
