Method Detail

send

boolean send(Message<?> message)
Send a Message to this channel. May throw a RuntimeException for non-recoverable errors. Otherwise, if the Message cannot be sent for a non-fatal reason this method will return 'false', and if the Message is sent successfully, it will return 'true'.

Depending on the implementation, this method may block indefinitely. To provide a maximum wait time, use send(Message, long).

Parameters:
message - the Message to send
Returns:
whether the Message has been sent successfully

send

boolean send(Message<?> message,
             long timeout)
Send a message, blocking until either the message is accepted or the specified timeout period elapses.

Parameters:
message - the Message to send
timeout - the timeout in milliseconds
Returns:
true if the message is sent successfully, false if the specified timeout period elapses or the send is interrupted
