- com.facebook.litho.LithoLayoutResult

All Implemented Interfaces:

ComponentLayout, LayoutResult

Direct Known Subclasses:

NestedTreeHolderResult
```
public class LithoLayoutResult
extends java.lang.Object
implements ComponentLayout, LayoutResult
```
This is the default implementation of a LayoutResult for Litho. This holds a reference to the LithoNode which created it, its YogaNode, and a list of its children.
