Thank you all for "trying to understand me" and helping me, I know I haven't
explained myself very well đ. Surely the implementation of my templates
(Controllers and Models) is not the most correct.
I'll try to explain myself better...
I have several types of use of the " ... args" parameters:
1.- Methods/Functions in base class that are overridden in child classes and
may or may not have fixed parameters, and a final parameter "... args":
1.1.- protected function fn_TypeA( ... args):void { }
override protected function fn_TypeA( ... args):void {
super.fn_TypeA.apply(this, args); // As Josh commented.
}
1.2.- protected function fn_TypeB(par1:int, par2:string, ... args):void
{ }
override protected function fn_TypeB(par1:int, par2:string, ...
args):void {
super.fn_TypeB.apply(this, [par1, par2].concat(args));
// As Greg commented, I haven't been able to test this yet, but I'm sure it's
correct đ
}
2.- Methods/Functions within a class, which may or may not override the base
class: (I show a real example)
In the base class I have these functions:
public function itemFilterDefault(... args):ICTypeArqParams {
// I can't implement it like this because I get an error
"retriveNewItemFilterDefault is not a function"
// var item:ICTypeArqParams =
retriveNewItemFilterDefault.apply(this,args);
var item:ICTypeArqParams = retriveNewItemFilterDefault(args);
if (pagination) {
item.pageSize = pageSize;
item.pageIndex = -1;
}else{
item.pageSize = -99;
item.pageIndex = -99;
}
return item;
}
public function retriveNewItemFilterDefault(... args):ICTypeArqParams{
return null; } // This function is the one that will normally be overridden in
child classes
2.1.- In a daughter class I have:
override public function itemFilterDefault(... args):ICTypeArqParams {
return super.itemFilterDefault.apply(this,args) as
CTypeParSegUserNet;
}
override public function retriveNewItemFilterDefault(...
args):ICTypeArqParams
{
return new CTypeParSegUserNet(args);
}
2.2.- In another daughter class I could have:
override public function itemFilterDefault(... args):ICTypeArqParams {
return super.itemFilterDefault.apply(this,args) as
CTypeParSegUserNet;
}
override public function retriveNewItemFilterDefault(...
args):ICTypeArqParams
{
var it:CTypeParSegUserNet = getSpecialitem("typeA", args); // I
can't use apply because I get an error "it's not a function"
return it;
}
private function getSpecialitem(type:String, ...
args):CTypeParSegUserNet
{
var it:CTypeParSegUserNet = new CTypeParSegUserNet(args);
if( type == "typeA")
It.level = 5;
else
It.level = 1;
return it;
}
I hope I have been clearer with these examples.
Thank you very much for your attention and help.

Asunto: Re: Parameters of type paramArray
Not knowing exactly what the method signature for 'fn_hello' is makes it a
little uncertain to advise, but it seems like you might want this
super.fn_hello.apply(this,[index].concat(args))
instead of
super.fn_hello.apply(index,[this].concat(args))
