Detailed Description

Base class for most ITK classes.

Object is the second-highest level base class for most itk objects. It extends the base object functionality of LightObject by implementing callbacks (via object/observer), debug flags/methods, and modification time tracking. Most ITK classes should be a subclass of Object due to the need to keep track of modified time.

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)		const

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff ( ) const

virtual

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const

virtual

Turn debugging output on.

Command* itk::Object::GetCommand ( unsigned long tag )

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to assign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::Object::GetDebug ( ) const

Get the value of the debug flag.

static bool itk::Object::GetGlobalWarningDisplay ( )

static

MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void )

Returns: A reference to this objects MetaDataDictionary.

Warning: This reference may be changed.

const MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void ) const

Returns: A constant reference to this objects MetaDataDictionary.

virtual ModifiedTimeType itk::Object::GetMTime ( ) const

virtual

Return this objects modified time.

Referenced by itk::SpatialObject< TMesh::PointDimension >::GetObjectMTime().

virtual const char* itk::Object::GetNameOfClass ( ) const

virtual

Standard part of all itk objects.

Reimplemented from itk::LightObject.

virtual const TimeStamp& itk::Object::GetTimeStamp ( ) const

virtual

Return this object's time stamp.

Reimplemented in itk::RealTimeClock.

bool itk::Object::HasObserver ( const EventObject & event ) const

Return true if an observer is registered for this event.

void itk::Object::InvokeEvent ( const EventObject & )

Call Execute on all the Commands observing this event id.

void itk::Object::InvokeEvent ( const EventObject & ) const

Call Execute on all the Commands observing this event id. The actions triggered by this call doesn't modify this object.

virtual void itk::Object::Modified ( ) const

virtual

Update the modification time for this object. Many filters rely on the modification time to determine if they need to recompute their data.
