net.rim.device.api.animation
Class AnimationValue

java.lang.Object
  extended by net.rim.device.api.animation.AnimationValue

public class AnimationValue
extends Object

Defines an interface for an object value that gets passed to the Animatable target during animation, allowing the target to get or set animation values for the property that is currently being animated.

The data in this container is stored as floating point data. However, there are getInt() and setInt() methods available that support rounding.

Updating The Target Property's Presentation Value

 public void setAnimationValue(int property, AnimationValue value)
 {
     switch(property) 
     {
         
         case ANIMATION_PROPERTY_XY:
             this.x = value.getFloat(0);
             this.y = value.getFloat(1);
             break;
         case ANIMATION_PROPERTY_WIDTH:
             this.width = value.getFloat(0);
             break;
         case ANIMATION_PROPERTY_HEIGHT:
             this.height = value.getFloat(0);
             break;
         
         _propertyDirty = true;
     }
 }

Getting The Target Property's Presentation Value

 public void getAnimationValue(int property, AnimationValue value)
 {
     switch(property) 
     {
         case ANIMATION_PROPERTY_XY:
             value.setFloat(0, this.x);
             value.setFloat(1, this.y);
             break;
         case ANIMATION_PROPERTY_WIDTH:
             value.setFloat(0, this.width);
             break;
         case ANIMATION_PROPERTY_HEIGHT:
             value.setFloat(0, this.height);
             break;
     }
 }
