Hi Iiley,
I am assuming you mean "extend a dynamically loaded class at runtime."
(Otherwise, of course, you can use regular compile-time inheritance to
extend classes you include in your DLL swfs.)
You can "extend" a dynamically loaded class at runtime if you use the
first method and mark it as "dynamic intrinsic".
eg.
// You must define intrinsic classes if you want type checking to work
with dynamically loaded classes
// If you make it *dynamic* also, you can extend it after loading it
into your app.
dynamic intrinsic class com.ariaware.tests.dll.library.FirstClass
{
public function aMethod():Void;
}
Then, once it's been loaded, you can extend it using the good 'ol
AS1-style prototype object:
eg.
// Called when the DLL has completely loaded
private function dllComplete ( evt:DLLEvent )
{
//...
//
// Extend the library classes
//
FirstClass.prototype.aNewMethod = function ()
{
trace ("AS1 style baby!");
};
//
// Test the library classes
//
var firstClass:FirstClass = new FirstClass();
firstClass.aMethod();
firstClass.aNewMethod();
//...
}
I just wrote up a blog post on it. You can download the updated example
files from there:
