String Strategy Test

The test of the applied Strategy design pattern uses two objects (Example 11-33).

The first object instantiates the concrete context class,Checker, and the second uses

Passwork.

{

this.type=TextFieldType.DYNAMIC;
this.multiline=true;
this.wordWrap=true;
this.border=true;
this.borderColor=0xcccccc;
}
}
}

Example 11-32. TextShow.as

package
{
import flash.text.TextFormat;

class TextShow extends TextFormat
{
function TextShow( ):void
{
this.font="Verdana";
this.color=0xcc0000;
this.size=11;
this.leading=3;
this.leftMargin=11;
this.rightMargin=6;
}
}
}

Example 11-33. TestStringStrategy.as

package
{
import flash.display.Sprite;

public class TestStringStrategy extends Sprite
{
private var showText:ShowText;
private var showText2:ShowText;
private var textShow:TextShow;

public function TestStringStrategy( ):void

Example 11-31. ShowText.as (continued)
