Animation

@JvmDefaultWithCompatibility
public interface Animation<T, V : AnimationVector>

This interface provides a convenient way to query from an VectorizedAnimationSpec or FloatDecayAnimationSpec: It spares the need to pass the starting conditions and in some cases ending condition for each value or velocity query, and instead only requires the play time to be passed for such queries.

The implementation of this interface should cache the starting conditions and ending conditions of animations as needed.

Note: Animation does not track the lifecycle of an animation. It merely reacts to play time change and returns the new value/velocity as a result. It can be used as a building block for more lifecycle aware animations. In contrast, Animatable and Transition are stateful and manage their own lifecycles.

Functions

public fun getValueFromNanos(playTimeNanos: Long): T

Returns the value of the animation at the given play time.

Parameters

public fun getVelocityVectorFromNanos(playTimeNanos: Long): V

Returns the velocity (in AnimationVector form) of the animation at the given play time.

Parameters

public fun isFinishedFromNanos(playTimeNanos: Long): Boolean

Returns whether the animation is finished at the given play time.
