vtkInformationKey

Section: Visualization Toolkit Common Classes

Usage

vtkInformationKey is the superclass for all keys used to access the map represented by vtkInformation. The vtkInformation::Set and vtkInformation::Get methods of vtkInformation are accessed by information keys. A key is a pointer to an instance of a subclass of vtkInformationKey. The type of the subclass determines the overload of Set/Get that is selected. This ensures that the type of value stored in a vtkInformation instance corresponding to a given key matches the type expected for that key.

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

  obj = vtkInformationKey
