ActionScript 3.0 Design Patterns

Encapsulation | 23

Example 1-11 and Example 1-12 show how you can lock up your encapsulated

objects using getters and setters with theget andset methods.

In Example 1-12, keep in mind thatflowersis a method, and not a property. How-

ever, setting and getting values using theflowers( )method looks exactly like setting

and getting a property value.

Example 1-11. FlowerShop.as

package
{
public class FlowerShop
{
private var buds:String;

public function FlowerShop( ):void {}

//Getter function
public function get flowers( ):String
{
return buds;
}

//Setter function
public function set flowers(floral:String):void
{
buds=floral;
}
}
}

Example 1-12. Send Flowers.as

package
{
import flash.display.Sprite;

public class SendFlowers extends Sprite
{
public function SendFlowers( )
{
var trueLove:FlowerShop = new FlowerShop( );
//Set values
trueLove.flowers="A dozen roses";
//Get values
trace(trueLove.flowers);
//Set different values
trueLove.flowers="And a dozen more....";
//Get the changed values
trace(trueLove.flowers);
}
}
}
