Interface IlvOptimizedAnimatedGraphic

public interface IlvOptimizedAnimatedGraphic

The interface IlvOptimizedAnimatedGraphic must be implemented by subclasses of IlvGraphic that want to provide two ways to draw an object: one for regular drawing, the other for drawing during animation. Animation mode is automatically enabled at the beginning of animation, and disabled at the end of animation by the manager animator. This is useful if regular drawing is very slow, because as a consequence animation will be slow. For example, instead of drawing a complex icon during animation, it may be sufficient to draw only a rectangle as an approximation. Example:

 public class MyIcon extends IlvIcon implements IlvOptimizedAnimatedGraphic
 {
   boolean animationDrawingMode = false;

   public void setAnimationDrawingMode(boolean flag)
   {
     animationDrawingMode = flag;
   }

   public void draw(Graphics dst, IlvTransformer t)
   {
     if (animationDrawingMode) {
       // fast: draw only rectangle. This is used during animation.
       dst.setColor(Color.black);
       IlvRect rect = boundingBox(t);
       dst.drawRect(rect.xFloor(), rect.yFloor(),
                    rect.widthFloor()+1, rect.heightFloor()+1);
     } else {
       // slow: draw all details
       super.draw(dst, t);
     }
   }
 }

Method Detail

setAnimationDrawingMode

void setAnimationDrawingMode(boolean flag)

Puts the object in animation mode. In animation mode, the drawing process is much faster.
