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.

• Observe an event

Member Function Documentation

virtual void itk::Command::Execute	(	Object *	caller,
		const EventObject &	event
	)		[pure virtual]

Abstract method that defines the action to be taken by the command.

Implemented in itk::CStyleCommand, itk::SimpleConstMemberCommand< T >, itk::SimpleMemberCommand< T >, itk::ReceptorMemberCommand< T >, itk::MemberCommand< T >, itk::CommandIterationUpdate< TOptimizer >, itk::CommandVnlIterationUpdate< TOptimizer >, and itk::WatershedMiniPipelineProgressCommand.

virtual void itk::Command::Execute	(	const Object *	caller,
		const EventObject &	event
	)		[pure virtual]

Abstract method that defines the action to be taken by the command. This variant is expected to be used when requests comes from a const Object
