Detailed Description

Generates a structured extent from unstructured.

vtkExtentTranslator generates a structured extent from an unstructured extent. It uses a recursive scheme that splits the largest axis. A hard coded extent can be used for a starting point.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.
