I'm having some frustrating problems with scope in trying to author
some classes. Basically, how do I get a value which is nested in a
function, returned to update the value of a given property? I've got
several functions nested inside a public function which includes
function literals. In the following code I just want to be able to
have the returnBW function update the value of the vidQuality
property. But I can't figure out how to return it? Any knowledge?
thanks.
class classes.CheckBW {
var nc:NetConnection;
var ns:NetStream;
var whichServer;
var counter;
var vidQuality:String;
public function bwCheck(whichServer):Void{
nc = new NetConnection();
nc.onStatus = function(info) {
trace("Level: "+info.level+" Code: "+info.code);
NetConnection.prototype.onBWDone = function(p_bw) {
trace("onBWDone: "+p_bw);
if (p_bw != undefined) {
returnBW(p_bw);
}
};
function returnBW(p_bw) {
trace("returnBW called");
if (p_bw>=400) {
vidQuality =
"_med";
} else if (p_bw<400 && p_bw>=150) {
vidQuality =
"_low";
} else if (p_bw<150) {
vidQuality =
"_low";
}
}
NetConnection.prototype.onBWCheck = function() {
return ++counter;
// Serverside, just ignore any
return value and return the call count
};
};
nc.connect(whichServer);
nc.call("checkBandwidth", null);
}
}
