PetscObjectIncrementTabLevel#

Increments the number of tabs that PETSCVIEWERASCII output for that object use based on the tablevel of another object. This should be called immediately after the object is created.

Synopsis#

#include "petscsys.h"    
PetscErrorCode PetscObjectIncrementTabLevel(PetscObject obj, PetscObject oldobj, PetscInt tab)

Not Collective

Input Parameters#

  • obj - any PETSc object where we are changing the tab

  • oldobj - the object providing the tab, optional pass NULL to use 0 as the previous tablevel for obj

  • tab - the increment that is added to the old objects tab

Note#

this is used to manage the output from options that are embedded in other objects. For example the KSP object inside a SNES object. By indenting each lower level further the hierarchy of objects is clear.
