Detailed Description

The "DelayedReturn" class implements delayed returning from functions.

For instance, suppose you would like to return from a wait() operation only after a certain time has passed, without blocking other clients from using your interface during this time.

Your implementation (in the skel file) of wait should look like this

 static DelayedReturn *delayedReturn = 0;

 bool TimeServer::waitUntil(long time)
 {
     if(time(0) < time)
     {
     	   // ... initialize timer here ...
         delayedReturn = Dispatcher::the()->delayReturn();
     }
     return false; 
 }

 void timerEvent()
 {
 	   delayedReturn->doReturn(true);
 }

NOTE: this class breaks for local use (i.e. you can only use it if the call was a remote call), so it is strongly recommended not to use it unless there is no alternative (and you should really know what you are doing, too).
