C# 클래스 EXILANT.Labs.CoAP.Channels.TimedQueue

In CoAP, confirmable messages must wait for an ACK or RST. As long as we do not receive ACK or RST we continue to send the confirmable message, provided, we have not exhausted the maximum number of retries. This queue maintains a list of confirmable messages that are waiting for ACK or RST If we do not receive the response within the timeout, this queue raises a timed-out event

AddToWaitQ ( AbstractCoAPMessage coapMsg ) : void	Add message to wait queue
GetInUseMessageIDs ( ) : ArrayList	Each CON/NON message is associated with a message ID. CON messages cannot be discarded unless ACK/RST is received or delivery attempt fails. This method tells us which message IDs are associated with pending CON messages
GetRequestPendingResponse ( UInt16 msgId ) : CoAPRequest	Get the request message that was pending response
RemoveFromWaitQ ( UInt16 msgId ) : void	Remove message from wait queue
Shutdown ( ) : void	Shutdown the polling
TimedQueue ( uint minTimeoutSecs ) : System	We start a thread here that keeps polling the confirmable messages It checks if the message timed-out, and if yes, raises the timeout event
