Remarks
The Item ID identifies the document in the hierarchy.
This method invokes the IVsHierarchy interface.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnHierarchyChanged method also allows derived classes to handle the event without attaching a delegate. This technique is recommended for handling the event in a derived class.
Notes to Inheritors:
When you override OnHierarchyChanged in a derived class, be sure to call the base class’s OnHierarchyChanged method so that registered delegates receive the event.
