public interface KeyPathElement

Any item that can be a part of a KeyPath should implement this.

Method Summary

Modifier and Type	Method	Description
<T> void	addValueCallback(T property, LottieValueCallback<T> callback)	The overridden method should handle appropriate properties and set value callbacks on their animations.
void	resolveKeyPath(KeyPath keyPath, int depth, List<KeyPath> accumulator, KeyPath currentPartialKeyPath)	Called recursively during keypath resolution.

Method Detail

resolveKeyPath

void resolveKeyPath(KeyPath keyPath,
                    int depth,
                    List<KeyPath> accumulator,
                    KeyPath currentPartialKeyPath)

Called recursively during keypath resolution.

The overridden method should just call: MiscUtils.resolveKeyPath(keyPath, depth, accumulator, currentPartialKeyPath, this);

Parameters:

keyPath - The full keypath being resolved.

depth - The current depth that this element should be checked at in the keypath.

accumulator - A list of fully resolved keypaths. If this element fully matches the keypath then it should add itself to this list.

currentPartialKeyPath - A keypath that contains all parent element of this one. This element should create a copy of this and append itself with KeyPath#addKey when it adds itself to the accumulator or propagates resolution to its children.

addValueCallback

<T> void addValueCallback(T property,
                          @Nullable
                          LottieValueCallback<T> callback)

The overridden method should handle appropriate properties and set value callbacks on their animations.
