Detailed Description

superclass for callback/observer methods.

vtkCommand is an implementation of the command design pattern that is used in callbacks (such as StartMethod(), ProgressMethod(), and EndMethod()) in VTK. vtkObject implements a Subject/Observer pattern. When a subject needs to notify a observer, it does so using a vtkCommand.
