public Message<?> preSend(Message<?> message,
                          MessageChannel channel)
```
    Description copied from interface: ChannelInterceptor
    Invoked before the Message is actually sent to the channel. This allows for modification of the Message if necessary. If this method returns null then the actual send invocation will not occur.
    Specified by:
    preSend in interface ChannelInterceptor
  - postSend
```
public void postSend(Message<?> message,
                     MessageChannel channel,
                     boolean sent)
```
    Description copied from interface: ChannelInterceptor
    Invoked immediately after the send invocation. The boolean value argument represents the return value of that invocation.
    Specified by:
    postSend in interface ChannelInterceptor
  - afterSendCompletion
```
public void afterSendCompletion(Message<?> message,
                                MessageChannel channel,
                                boolean sent,
                                Exception ex)
```
    Description copied from interface: ChannelInterceptor
    Invoked after the completion of a send regardless of any exception that have been raised thus allowing for proper resource cleanup.
    Note that this will be invoked only if ChannelInterceptor.preSend(org.springframework.messaging.Message<?>, org.springframework.messaging.MessageChannel) successfully completed and returned a Message, i.e. it did not return null.
    Specified by:
    afterSendCompletion in interface ChannelInterceptor
  - preReceive
```
public boolean preReceive(MessageChannel channel)
```
    Description copied from interface: ChannelInterceptor
    Invoked as soon as receive is called and before a Message is actually retrieved. If the return value is 'false', then no Message will be retrieved. This only applies to PollableChannels.

    preReceive in interface ChannelInterceptor
  - postReceive

public Message<?> postReceive(Message<?> message,
                              MessageChannel channel)
