public class FluxMessageChannel
extends AbstractMessageChannel
implements org.reactivestreams.Publisher<Message<?>>, ReactiveStreamsSubscribableChannel, Lifecycle

Method Details

doSend

protected boolean doSend(Message<?> message,
 long timeout)

Description copied from class: AbstractMessageChannel

Subclasses must implement this method. A non-negative timeout indicates how long to wait if the channel is at capacity (if the value is 0, it must return immediately with or without success). A negative timeout value indicates that the method should block until either the message is accepted or the blocking thread is interrupted.

Specified by:

doSend in class AbstractMessageChannel

Parameters:

message - The message.

timeout - The timeout.

Returns:

true if the send was successful.

subscribe
