It looks like a singleton, all be it a weird way of making one. Usually you
would have the instance variable as private & access it with a getter
function like:
class MyTestClass
{
private var _instance: MyTestClass;
public function getInstance():MyTestClass{
if(_instance == null){
_instance = new MyTestClass();
}
Return _instance;
}
private function MyTestClass() {trace ("Created")}
public function runTest(){trace("running test")}
}
///////////////////////
MyTestClass.getInstance().runTest();
This is a well used design pattern that I am sure you can find a tutorial on
in google. Basically they are used where you will only ever need one
instance of a class say a timeline.

Subject: [Flashcoders] Weird OOP ability... Need a description of why,or at
least some documentation
I ran across this really bizarre method access while reviewing someone
else's work.
I would like to look up some documentation for this syntax (it doesn't
have to be AS, it could be some other OOP language - if this is a standard
option that I haven't seen before)... or at least get a description of
why/how it works (other then the obvious - that it does).
Also, can anyone give any good reason to use this syntax?
I'm just confused by it.
Thanks!
Cheerio!

Notice that it does NOT use static's
////////////////////////
class MyTestClass
{
function MyTestClass() {trace ("Created")}
public function runTest(){trace("running test")}
}
///////////////////////
var myInst:MyTestClass = new MyTestClass();
MyTestClass(myInst).runTest();
