AS3 how to return EventListener value

Question

If I have code that looks like this:

public function getNetStreamPublishClientList():Array
{
    var ncStreamListResults = new Object()
    ncStreamListResults.onResult = function(list:Array)
    {
        //this needs to be returned from getNetStreamPublishClientList
        return list;
    }

    this.nc.call("getStreamClientIds", 
                 new Responder(ncStreamListResults.onResult),
                 this.streamName);
}

how can I return the value of list from getNetStreamPublishClientList?

Answer 1

use global item for list

Answer 2

It looks like you won't be able to know the value of list at the point that getNetStreamPublishClientList() finishes executing.

This is because the nc object will probably not have finished its work by that time, and in that case the completion handler (currently assigned to be onResult) won't have been called.

Whatever is waiting on the result of this function, I'd change it to wait for an event. Possibly use a member function to act as the onResult handler.
