Set the NetStream object's client property to an Object

By setting the client property to either an Object or a subclass of NetStream, you can reroute the onMetaData and onCuePoint callback methods or ignore them completely. The following example demonstrates how you can use an empty Object to ignore the callback methods without listening for the asyncError event:

var nc:NetConnection = new NetConnection();
nc.connect(null);

var customClient:Object = new Object();

var ns:NetStream = new NetStream(nc);
ns.client = customClient;
ns.play("video.flv");

var vid:Video = new Video();
vid.attachNetStream(ns);
addChild(vid);

If you wanted to listen for either the onMetaData or onCuePoint callback methods, you would need to define methods to handle those callback methods, as shown in the following snippet:

var customClient:Object = new Object();
customClient.onMetaData = metaDataHandler;
function metaDataHandler(infoObject:Object):void
{
    trace("metadata");
}

The previous code listens for the onMetaData callback method and calls the metaDataHandler() method, which traces a string. If Flash Player encountered a cue point, no errors would be generated even though no onCuePoint callback method is defined.
