I needed cloning with inheritance one time.
I did it this way.
Worked perfectly...
*************** ValueObject ************
class ValueObject{
public function clone
(parent:ValueObject):ValueObject{
var clone:ValueObject= new ValueObject();
return cloneParams(clone,parent);
}
public function cloneParams
(clone:ValueObject, parent:ValueObject):ValueObject{
clone.setParent(parent);
return clone;
}
private function cloneValueObjectArray
(arrVOs:Array, parent:ValueObject){
var cloneArray = undefined;
if (arrVOs != undefined){
cloneArray = new Array();
for (var i=0;i<arrVOs.length;i++)
{
if (arrVOs[i] != undefined){
var voClone:ValueObject =
ValueObject(arrVOs[i]).clone(parent);
cloneArray.push(voClone);
}else{
cloneArray.push(arrVOs[i]);
}
}
}
return cloneArray;
}
}
***************************
And in a subclass you do something like this:
************** SubClass: ************
...
public function clone(parent:ValueObject):ValueObject{
var clone:ValueObject= new SubClass();
return cloneParams(clone,parent);
}
public function cloneParams
(clone:ValueObject,parent:ValueObject):ValueObject{
clone = SubClass(super.cloneParams(clone,parent));
SubClass (clone).type = this.type;
SubClass (clone).name = this.name;
SubClass (clone).productID = this.productID;
SubClass (clone).pages =
cloneValueObjectArray(arrValueObjects,clone);
return clone;
}
...
