ParallaxTarget

public abstract class ParallaxTarget
extends Object

java.lang.Object
↳	android.support.v17.leanback.widget.ParallaxTarget

Known Direct Subclasses

ParallaxTarget is responsible for updating the target through the update(float) method or the directUpdate(Number) method when isDirectMapping() is true. When isDirectMapping() is false, ParallaxEffect transforms the values of Parallax, which represents the current state of UI, into a float value between 0 and 1. That float value is passed into update(float) method.
