Functions

afterReceiveCompletion

void afterReceiveCompletion(MessageBase message, MessageChannel channel, Exception ex)

Invoked after the completion of a receive regardless of any exception that have been raised thus allowing for proper resource cleanup. <p>Note that this will be invoked only if {@link #preReceive} successfully completed and returned {@code true}. @since 4.1

afterSendCompletion

void afterSendCompletion(MessageBase message, MessageChannel channel, bool sent, Exception ex)

Invoked after the completion of a send regardless of any exception that have been raised thus allowing for proper resource cleanup. <p>Note that this will be invoked only if {@link #preSend} successfully completed and returned a Message, i.e. it did not return {@code null}. @since 4.1

postReceive

MessageBase postReceive(MessageBase message, MessageChannel channel)

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

postSend

void postSend(MessageBase message, MessageChannel channel, bool sent)

Invoked immediately after the send invocation. The value argument represents the return value of that invocation.

preReceive

bool preReceive(MessageChannel channel)

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.

preSend

MessageBase preSend(MessageBase message, MessageChannel channel)

Invoked before the Message is actually sent to the channel. This allows for modification of the Message if necessary. If this method returns {@code null} then the actual send invocation will not occur.
