'Declaration Function IndexOf( _ ByVal node As IUIHierarchyNode _ ) As Integer

Implementations of IUIHierarchyNode that require the IndexOf method to function based on a node's value equivalency must override Equals and GetHashCode when their class implements IUIHierarchyNode, otherwise only reference comparison is performed by this method.
