Hi
I'm new to OOP programming in AS2.
I'm writing two classes right now. One which creates/manipulates an array
of XMLNodes and one which watches for an internet connection. When it finds
a connection, it starts to send the XMLNodes from the queue back to a
server one by one.
So far I've written the Queue class.
class com.Queue {
private var _milestoneXMLNode:XMLNode;
private var _aQueue:Array;
//Constructor
public function Queue() {
_aQueue = new Array();
}
//Methods
public function addMilestoneToQueue(milestoneXMLNode:XMLNode):Void {
_aQueue.push(milestoneXMLNode);
}
private function getQueue():Array {
return _aQueue;
}
private function getFirstMessageInQueue():XMLNode {
return _aQueue[0];
}
private function deleteFirstMessageFromQueue():Void {
_aQueue.splice(0,1)
}
}
Now the real question I have is how to get the first element from the
Queue, i.e. _aQueue[0] from the Queue class into the Connection class so
that it can be sent back to the server?
class com.Connection {
private var _isConnection:Boolean;
//Constructor
public function Connection() {
//No connection by default
_isConnection = false;
}
//Methods
private function detectConnection():Void {
//
}
}
How do I do this? Or does this break encapsulation? I'm a bit stuck, would
appreciate any advice.
Cheers
Andrew
