PetscObjectPrintClassNamePrefixType#

used in the XXXView() methods to display information about the class, name, prefix and type of an object

Synopsis#

#include "petscsys.h"   
PetscErrorCode PetscObjectPrintClassNamePrefixType(PetscObject obj, PetscViewer viewer)

Input Parameters#

obj - the PETSc object
viewer - PETSCVIEWERASCII viewer where the information is printed, function does nothing if the viewer is not PETSCVIEWERASCII type

Notes#

If the viewer format is PETSC_VIEWER_ASCII_MATLAB then the information is printed after a % symbol so that MATLAB will treat it as a comment.

If the viewer format is PETSC_VIEWER_ASCII_VTK*, PETSC_VIEWER_ASCII_LATEX, or PETSC_VIEWER_ASCII_MATRIXMARKET then don’t print header information as these formats can’t process it.

Developer Note#

The flag donotPetscObjectPrintClassNamePrefixType is useful to prevent double printing of the information when recursion is used to actually print the object.
