java.lang.Object

com.facebook.litho.widget.ComponentTreeHolder

public class ComponentTreeHolder
extends Object

A class used to store the data backing a RecyclerBinder. For each item the ComponentTreeHolder keeps the RenderInfo which contains the original Component and either the ComponentTree or the StateHandler depending upon whether the item is within the current working range or not.
