AS3,AIR,Socket. How to check the progress of a writeObject() transfer? - actionscript-3

Question

I'm dealing with AIR and Sockets, using a Server app and another as Client.
Server sends an object to Client:
clientSocket.writeObject(myObject);
Client has a listener, like this:
socket.addEventListener(ProgressEvent.SOCKET_DATA, socketData);
How can I know the size of the incoming object? I need to monitoring this process, cause when the transfer is complete I need to do another processes.
I tried this, but doesn't work :
var total:int = 0;
private function socketData(e:ProgressEvent) :void {
if (total == 0) {
total = socket.readInt();
}
if (socket.bytesAvailable >= total) {
trace('COMPLETE');
total = 0;
} else {
trace('progress:' + socket.bytesAvailable + ' | total: ' + total);
}
}
This post does not work in my specific case: AS3 / AIR readObject() from socket - How do you check all data has been received?

Answer 1

I resolve it, with a hack:
SERVER: Send an object:
clientSocket.writeObject(image);// var image:Bitmap
clientSocket.flush();
CLIENT:
A. Have a listener to receive socket data:
socket.addEventListener(ProgressEvent.SOCKET_DATA, socketData);
B. Receive the bytes. When all the bytes are available, then read the object:
private var prevBytes:int = -1;
private var currentBytes:int = 0;
private function onEnterFrame(e:Event):void {
if (currentBytes == prevBytes) {
removeEventListener(Event.ENTER_FRAME, onEnterFrame);
currentBytes = 0;
prevBytes = -1;
var obj:* = socket.readObject();
} else {
prevBytes = currentBytes;
}
trace('Current : ' + currentBytes + ' | Prev : ' + prevBytes);
}
private function socketData(e:ProgressEvent):void {
trace('on socketData : ' + currentBytes);
if (currentBytes == 0) {
addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
currentBytes = socket.bytesAvailable;
}
