Hi,
I am looking for advice about swapping classes of the same name but
using different methods.
Let's consider three classes:
class SomeClass
{
public function meth()
{
trace("meth of skin SomeClass VERSION 0");
}
}
//
class SomeClass
{
public function meth()
{
trace("meth of skin SomeClass VERSION 1");
}
}
//
class SomeClass
{
public function meth()
{
trace("meth of skin SomeClass VERSION 2");
someNewMethod();
}
private function someNewMethod()
{
trace("something new...");
}
}
The first of those is imported into a main.swf file. I can make an
instance:
var Q:SomeClass = new SomeClass();
Q.meth() // traces : meth of skin SomeClass VERSION 0
The next two classes are imported in: one storage1.swf and the other,
storage2.swf
Both .swf files are loaded into the main.swf. First the storage1.swf
and next storage2.swf. But before loading, I delete the class:
trace(SomeClass) // out: [type Function]
delete SomeClass
trace(SomeClass) // out: undefined
And after loading the storage1.swf I can make again an
instance of SomeClass:
var Q1:SomeClass = new SomeClass();
Q1.meth() // traces: meth of skin SomeClass VERSION 1
It uses a new version of meth().
Now I delete the SomeClass class:
delete SomeClass
... and load somewhere into the stage of main.swf the storage2.swf
file. After loading the first one I can make a new instance of
SomeClass:
var Q2:SomeClass = new SomeClass();
Q2.meth() // traces: meth of skin SomeClass VERSION 2
// something new...
and so on, deleting an loading a new version....
Now the question:
The same class name, the same method name, eventually other, new
methods of the same class and deleting the class.... Could this be a
good way to overwrite classes ? I tested it and works. Flash allows
deleting classes. But maybe I am not aware of some resulting problems.
Is is ok in terms of good programing practices ?
Thanks,
Greg
