Class RemoteRefPolling

java.lang.Object

org.nustaq.kontraktor.remoting.base.RemoteRefPolling

All Implemented Interfaces:

Runnable

public class RemoteRefPolling
extends Object
implements Runnable

polls queues of remote actor proxies and serializes messages to their associated object sockets. Note for transparent websocket/longpoll reconnect: Terminated / Disconnected remote actors (registries) are removed from the entry list, so regular actor messages sent to a terminated remote actor queue up in its mailbox. Callbacks/Future results from exported callbacks/futures still reach the object socket as these are redirected directly inside serializers. Those queue up in the webobjectsocket's list, as flush is not called anymore because of removement from SendLoop list. In case of TCP remoting, an ActorStopped Exception is thrown if an attempt is made to send a message to a disconnected remote actor. in short: regular messages to disconected remote actors queue up in mailbox, callbacks in object socket buffer For typical client/server alike use cases, there are never remote references as most client api's do not support handing out client remoterefs to servers (javascript, kontraktor bare)
