/**
* Base node class for representing virtual tree of React nodes. Shadow nodes are used primarily for
* layouting therefore it extends {@link YogaNode} to allow that. They also help with handling
* Common base subclass of {@link YogaNode} for all layout nodes for react-based view. It extends
* {@link YogaNode} by adding additional capabilities.
*
* <p>Instances of this class receive property updates from JS via @{link UIManagerModule}.
* Subclasses may use {@link #updateShadowNode} to persist some of the updated fields in the node
* instance that corresponds to a particular view type.
*
* <p>Subclasses of {@link ReactShadowNodeImpl} should be created only from {@link ViewManager} that
* corresponds to a certain type of native view. They will be updated and accessed only from JS
* thread. Subclasses of {@link ViewManager} may choose to use base class {@link
* ReactShadowNodeImpl} or custom subclass of it if necessary.
*
* <p>The primary use-case for {@link ReactShadowNodeImpl} nodes is to calculate layouting. Although
* this might be extended. For some examples please refer to ARTGroupYogaNode or ReactTextYogaNode.
*
* <p>This class allows for the native view hierarchy to not be an exact copy of the hierarchy
* received from JS by keeping track of both JS children (e.g. {@link #getChildCount()} and
* separately native children (e.g. {@link #getNativeChildCount()}). See {@link
* NativeViewHierarchyOptimizer} for more information.

* children of a view might be optimized away, so this could return the same value for multiple
* different children.
*
* <p>Example. Native children are represented by (N) where N is the no-opt child they came from.
* If no children are optimized away it'd look like this: (0) (1) (2) (3) ... (n)

* <p>In case some children are optimized away, it might look like this: (0) (1) (1) (1) (3) (3)
