Detailed Description

superclass for callback/observer methods

Command is an implementation of the command design pattern that is used in callbacks (such as StartMethod(), ProgressMethod(), and EndMethod()) in ITK. itkObject implements a Subject/Observer pattern. When a subject needs to notify a observer, it does so using a itkCommand. The Execute method is called to run the command.
