vtkObject

Section: Visualization Toolkit Common Classes

Usage

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.

To create an instance of class vtkObject, simply invoke its constructor as follows

  obj = vtkObject

Methods

The class vtkObject has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, obj is an instance of the vtkObject class.
