I've asked this same question with Python.
Now I like to know if this can be done in AS3.
If I have something like this:
package
{
public class SomeClass
{
private function A():void { C() }
private function B():void { C() }
private function C():void
{
// who is the caller, A or B ???
}
public function SomeClass()
{
A()
B()
}
}
}
Despite the design or other issues, this is only a question of an inquiring mind.
Note: I like to have an 开发者_JS百科access to an instance of the caller function so I can call that caller function (if I want to)
Note 2 : This has to be done without changing function C()
signature
"Unlike previous versions of ActionScript, ActionScript 3.0 has no arguments.caller property. To get a reference to the function that called the current function, you must pass a reference to that function as an argument."
From http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/arguments.html
That's the only way you can do that, otherwise you'll need to make a global variable to tell what function is calling C
Sure it can be done. You can do something like
private function C():void
{
var e:Error = new Error();
var stack:String = e.getStackTrace();
//analyze stack and find out which function called it.
}
this is ugly but it would work.
