Class MultiMessageCallback

java.lang.Object

freenet.node.MultiMessageCallback

Direct Known Subclasses:

WaitingMultiMessageCallback

public abstract class MultiMessageCallback
extends java.lang.Object

Groups a set of message sends together so that we get a single sent(boolean) callback after all the messages have been sent, and then later a finished(boolean). None of the callbacks will be called until after you call arm(). Typical usage:

Message m1 = ...;
 Message m2 = ...;
 PeerNode pn = ...;
 MultiMessageCallback mcb = new MultiMessageCallback() {
   protected void finish(boolean success) {
     // Messages have finished.
   }
   protected void sent(boolean success) {
     // Messages have been sent.
   }
 }
 pn.sendAsync(m1, mcb.make(), ctr);
 pn.sendAsync(m2, mcb.make(), ctr);
 mcb.arm();

Add another message. You should call arm() after you have added all messages.

True if the callbacck has finished (and is armed)
