FLASH® LITE™ 2.x - Adobe Help and Support

The following example shows how to override toString() in a custom class. First create a
text file named Vehicle.as that contains only the Vehicle class definition and place it into your
Classes folder inside your Configuration folder.
// contents of Vehicle.as
class Vehicle {
var numDoors:Number;
var color:String;
function Vehicle(param_numDoors:Number, param_color:String) {
this.numDoors = param_numDoors;
this.color = param_color;
}
function toString():String {
var doors:String = "door";
if (this.numDoors > 1) {
doors += "s";
}
return ("A vehicle that is " + this.color + " and has " + this.numDoors +
" " + doors);
}
}
// code to place into a FLA file
var myVehicle:Vehicle = new Vehicle(2, "red");
trace(myVehicle.toString());
// output: A vehicle that is red and has 2 doors
// for comparison purposes, this is a call to valueOf()
// there is no primitive value of myVehicle, so the object is returned
// giving the same output as toString().
trace(myVehicle.valueOf());
// output: A vehicle that is red and has 2 doors
