#include <itkCommand.h>

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. itk::Object implements a Subject/Observer pattern. When a subject needs to notify a observer, it does so using a itk::Command. The Execute method is called to run the command.
