+/**
+ * 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.
+ *
+ *
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.
+ *
+ *
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.
+ *
+ *
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.
+ *
+ *
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.

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