Hello :)
1 - in AS1 you can use addProperty with the prototype and not in the
constructor !!
// ----o Constructor
_global.Square= function(side)
{
this.side=side
}
// ----o Public Methods
Square.prototype.getArea=function()
{
return Math.pow(this.side,2);
}
Square.prototype.setArea = function(area)
{
this.side=Math.sqrt(area) ; // don't forget "Math" and not "math" !!!
}
// ----o Virtual Properties
Square.prototype.addProperty("area", Square.prototype.getArea,
Square.prototype.setArea) ;
2 - In AS2 you have 2 methods to create Virtual Properties
2 - 1 with get and set keywords
class Square
{
// ----o Constructor
public function Square(side:Number)
{
this.side = side ;
}
// ----o Public Properties
public var side:Number ;
// ----o Virtual Properties
public function get area()
{
return Math.pow(this.side,2);
}
public function set area ( area )
{
side = Math.sqrt(area) ;
}
}
2 - 2 with addProperty method
class Square
{
// ----o Constructor
public function Square(side:Number)
{
this.side = side ;
}
// ----o Public Properties
public var side:Number ;
// ----o Public Methods
public function getArea()
{
return Math.pow(this.side,2);
}
public function setArea ( area )
{
side = Math.sqrt(area) ;
}
// ----o Virtual Properties
static private var __AREA__:Boolean = Square.prototype.addProperty("area",
Square.prototype.getArea ,Square.prototype.setArea) ;
}
EKA+ :)
2006/9/25, [EMAIL PROTECTED] <[EMAIL PROTECTED]>:
I know AddProperty was useful in creating getter/setters when defining AS1
based classes
ie
//CODE BEGIN
//create a new square class
_global.Square= function(side){
this.side=side
this.addProperty("area",this.getArea,this.setArea);
}
Square.prototype.setArea=function(area){
this.side=math.sqrt(area);
}
Square.prototype.getArea=function(){
return Math.pow(this.side,2);
}
//CODE END
Is this same AddProperty technique useful with AS2 classes?
