Method Detail

preSend

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

Deprecated.

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)

Deprecated.

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,
                                @Nullable
                                Exception ex)

Deprecated.

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)

Deprecated.

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.

Specified by:

preReceive in interface ChannelInterceptor

postReceive

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

Deprecated.

Description copied from interface: ChannelInterceptor

Invoked immediately after a Message has been retrieved but before it is returned to the caller. The Message may be modified if necessary; null aborts further interceptor invocations. This only applies to PollableChannels.

Specified by:

postReceive in interface ChannelInterceptor

afterReceiveCompletion

public void afterReceiveCompletion(@Nullable
                                   Message<?> message,

Deprecated.

Description copied from interface: ChannelInterceptor
