Using Concrete Decorator Classes - Deadly sins
(Page 2 of 4 )
Example 4-29. Rage.as
package
{
public class Rage extends Decorator
{
private var components:Component;
public function Rage(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Rage";
}
override public function good():Number
{
return -9 + components.good();
}
override public function evil():Number
{
return 8 + components.evil();
}
}
}
Example 4-30. Malice.as
package
{
public class Malice extends Decorator
{
private var components:Component;
public function Malice(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Malice";
}
override public function good():Number
{
return -14 + components.good();
}
override public function evil():Number
{
return 12 + components.evil();
}
}
}
Example 4-31. Prejudice.as
package
{
public class Prejudice extends Decorator
{
private var components:Component;
public function Prejudice(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Prejudice";
}
override public function good():Number
{
return -10 + components.good();
}
override public function evil():Number
{
return 15 + components.evil();
}
}
}
Example 4-32. Obfuscation.as
package
{
public class Obsfuscation extends Decorator
{
private var components:Component;
public function Obsfuscation(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Obsfuscation";
}
override public function good():Number
{
return -12 + components.good();
}
override public function evil():Number
{
return 7 + components.evil();
}
}
}
Example 4-33. Dogmatisms.as
package
{
public class Dogmatisms extends Decorator
{
private var components:Component;
public function Dogmatisms(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Dogmatisms";
}
override public function good():Number
{
return -12 + components.good();
}
override public function evil():Number
{
return 15 + components.evil();
}
}
}
Example 4-34. Arrogance.as
package
{
public class Arrogance extends Decorator
{
private var components:Component;
public function Arrogance(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Arrogance";
}
override public function good():Number
{
return -5 + components.good();
}
override public function evil():Number
{
return 5 + components.evil();
}
}
}
Example 4-35. Indifference.as
package
{
public class Indifference extends Decorator
{
private var components:Component;
public function Indifference(components:Component)
{
this.components=components;
}
override public function getSoul():String
{
return components.getSoul() + "|Indifference";
}
override public function good():Number
{
return -9 + components.good();
}
override public function evil():Number
{
return 10 + components.evil();
}
}
}
At this point you can add your own concrete decorators. Use the same format as the others. You can also add additional concrete components. So instead of just Dick and Jane, you can add others you’d like to decorate with good and evil.
