Interface AnimationBinding

All Known Implementing Classes:

BezierTransition, DelayBinding, ParallelBinding, SequenceBinding, SpringTransition, TimingTransition, TransitionAnimationBinding

public interface AnimationBinding

An animation or set of animations using GraphBindings. In start(com.facebook.litho.animation.Resolver), subclasses can use the provided Resolver instance to reference concrete mount item properties when creating the GraphBinding.

Method Summary

Modifier and Type	Method and Description
void	addListener(AnimationBindingListener animationBindingListener) Adds a AnimationBindingListener.
void	collectTransitioningProperties(java.util.ArrayList<PropertyAnimation> outList) Collects the set of PropertyAnimations that this animation will animate.
java.lang.Object	getTag() Allows adding a tags that can also be used to store data without resorting to another data structure.
boolean	isActive()
void	prepareToStartLater() Called when binding is to be started later.
void	removeListener(AnimationBindingListener animationBindingListener) Removes a previously added AnimationBindingListener.
void	setTag(java.lang.Object tag)
void	start(Resolver resolver) Starts this animation.
void	stop() Stops this animation.

Method Detail

prepareToStartLater

void prepareToStartLater()

Called when binding is to be started later. For example: when a set of bindings starts, but this particular binding will come into play later. This may be called multiple times in case of several nested sets

start

void start(Resolver resolver)

Starts this animation. The provided Resolver instance can be used to configure this animation appropriately using mount content property current and end values.

stop

void stop()

Stops this animation.

isActive

boolean isActive()

Returns:

whether this animation is running

collectTransitioningProperties

void collectTransitioningProperties(java.util.ArrayList<PropertyAnimation> outList)

Collects the set of PropertyAnimations that this animation will animate. This is used to make sure before/after values are recorded and accessible for the animation. Implementations should add their animating properties to this set.

Note: This is a 'collect' call instead of a getter to allocating more sets then necessary for animations with nested animation (e.g. a sequence of animations). Yay Java.

addListener

void addListener(AnimationBindingListener animationBindingListener)

Adds a AnimationBindingListener.

removeListener

void removeListener(AnimationBindingListener animationBindingListener)

Removes a previously added AnimationBindingListener.

getTag

java.lang.Object getTag()

Allows adding a tags that can also be used to store data without resorting to another data structure. *

setTag

void setTag(java.lang.Object tag)
