```
public class LottieComposition

                    
```
After Effects/Bodymovin composition model. This is the serialized model from which the animation will be created. It is designed to be stateless, cacheable, and shareable.
To create one, use LottieCompositionFactory.
It can be used with a com.airbnb.lottie.LottieAnimationView or com.airbnb.lottie.LottieDrawable.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public class`	`LottieComposition.Factory`	This will be removed in the next version of Lottie. LottieCompositionFactory has improvedAPI names, failure handlers, and will return in-progress tasks so you will never parse the sameanimation twice in parallel.

Method Detail

getPerformanceTracker

 PerformanceTracker getPerformanceTracker()

getPrecomps

@RestrictTo(value = RestrictTo.Scope.LIBRARY)@Nullable() List<Layer> getPrecomps(String id)

getImages
```
 Map<String, LottieImageAsset> getImages()
```
Returns a map of image asset id to LottieImageAsset. These assets contain image metadata exportedfrom After Effects or other design tool. The resulting Bitmaps can be set directly on the image asset sothey can be loaded once and reused across compositions.If the context dp scale has changed since the last time images were retrieved, images will be rescaled.
