Question

I have a class called socket.as and is responsible for socket connection etc. It has an event listener onSocketData, which is called whenever data is received. In my main class, Main.as, i have instantiated an object of socket class.

How can I get data from socket class? Do i have to create a custom event in Main.as that should be triggered by socket class?
Thank you.

below is the event listener from socket class:

private function onSocketData(event:ProgressEvent):void <br>
{
   //string sent over serial port.   
   var data:String = _socket.readUTFBytes( _socket.bytesAvailable );  

   var direction:int = 0;  

   buffer += data;  

 while((index = buffer.indexOf(EOL_DELIMITER)) > -1)
 {
  msg = buffer.substring(0, index-1);
  len = (buffer.indexOf(EOL_DELIMITER)) - 1;

  //remove the message from the buffer
  buffer = buffer.substring(index + 1);

  if ( msg != "off" )
  {
   button = parseInt(msg.substr(6, (len-8)));

   trace("Socket Data: " + msg + ", Button: " + button);
  }
 }
}

As you mention , you could create a CustomEvent that will be triggered by the Socket class or you could dispatch an Event from the Socket class , whenever data is available and use a getter to retrieve the variable.
