cool thanks guys ....I was trying a good way to figure out how to go about
abstract classes
so if the class is abstract I would do
public function AbstractList(){
throw new Error("Abstract class cannot be instantiated");
}
public function List(){
//what I need to
try{
super();
}
catch(err:Error){}
}
this seems to work fine
if anyone has a better suggestion I am all ears :)
cheers

'cos in every class unless you make an explicit call to super there
is an automatic implicit call to super() before anything else
executes in the subclass constructor.
The explicit call to super can include params as in super(x) if the
superclass has such a constructor.
One gotcha is if you extend a class that has a constructor that takes
an argument and decide not to override the constructor then you
extend that class you cant call super with an argument anymore ie
public class classA{
function classA(xx:int){}
...other stuff...
}
public class classB extends classA{
...only other stuff is overridden...
}
public class classC extends classB{
function classC(xx:int){
super(xx);//compile error.... no such constructor in classB
..do some stuff..
}
}
