Detailed Description

abstract base class for most VTK objects

vtkObject is the base class for most objects in the visualization toolkit. vtkObject provides methods for tracking modification time, debugging, printing, and event callbacks. Most objects created within the VTK framework should be a subclass of vtkObject or one of its children. The few exceptions tend to be very small helper classes that usually never get instantiated or situations where multiple inheritance gets in the way. vtkObject also performs reference counting: objects that are reference counted exist as long as another object uses them. Once the last reference to a reference counted object is removed, the object will spontaneously destruct.

Warning:: Note: in VTK objects should always be created with the New() method and deleted with the Delete() method. VTK objects cannot be allocated off the stack (i.e., automatic objects) because the constructor is a protected method.

virtual const char* vtkObject::GetClassName ( ) [virtual]

static int vtkObject::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

virtual int vtkObject::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

static vtkObject* vtkObject::SafeDownCast ( vtkObject * o ) [static]

static vtkObject* vtkObject::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObjectBase.

virtual void vtkObject::DebugOn ( ) [virtual]

Turn debugging output on.

Reimplemented in vtkImageOpenClose3D.

virtual void vtkObject::DebugOff ( ) [virtual]

Turn debugging output off.

Reimplemented in vtkImageOpenClose3D.

unsigned char vtkObject::GetDebug ( )

Get the value of the debug flag.

void vtkObject::SetDebug ( unsigned char debugFlag )

Set the value of the debug flag. A non-zero value turns debugging on.

static void vtkObject::BreakOnError ( ) [static]

This method is called when vtkErrorMacro executes. It allows the debugger to break on error.

virtual void vtkObject::Modified ( ) [virtual]

Update the modification time for this object. Many filters rely on the modification time to determine if they need to recompute their data. The modification time is a unique monotonically increasing unsigned long integer.

Reimplemented in vtkInformation, vtkImageOpenClose3D, vtkLightKit, and vtkLODActor.

virtual unsigned long vtkObject::GetMTime ( ) [virtual]

Return this object's modified time.

unsigned long vtkObject::AddObserver	(	unsigned long	event,
		vtkCommand *	,
		float	priority = `0.0f`
	)

Allow people to add/remove/invoke observers (callbacks) to any VTK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and a vtkCommand to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. When events are invoked, the observers are called in the order they were added. If a priority value is specified, then the higher priority commands are called first. A command may set an abort flag to stop processing of the event. (See vtkCommand.h for more information.) BTX
