/**
* 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.

* Returns the offset within the native children owned by all layout-only nodes in the subtree

* nodes (nodes not optimized out of the native tree) that are a) to the left (visited before by a
* DFS) of the given child in the subtree rooted at this node and b) do not have a native parent
* in this subtree (which means that the given child will be a sibling of theirs in the final
* native hierarchy since they'll get attached to the same native parent).
*
* <p>Basically, a view might have children that have been optimized away by {@link
* NativeViewHierarchyOptimizer}. Since those children will then add their native children to this
* view, we now have ranges of native children that correspond to single unoptimized children. The
* purpose of this method is to return the index within the native children that corresponds to
* the **start** of the native children that belong to the given child. Also, note that all of the
* 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)
* (4)
*
* <p>In that case: getNativeOffsetForChild(Node 0) => 0 getNativeOffsetForChild(Node 1) => 1
* getNativeOffsetForChild(Node 2) => 4 getNativeOffsetForChild(Node 3) => 4
