      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
      message - The message.
      timeout - The timeout.
      true if the send was successful.
