ISColoringViewFromOptions

Processes command line options to determine if/how an ISColoring object is to be viewed.

Synopsis

#include "petscis.h"  
PetscErrorCode ISColoringViewFromOptions(ISColoring obj, PetscObject bobj, const char name[])

Collective

Input Parameters

• obj - the ISColoring object

• bobj - object that provides the options database key prefix to use for viewing, or NULL to use prefix of obj

• name - option to activate viewing

Options Database Key

• -name viewer_specification - See PetscOptionsCreateViewer() for the values of viewer_specification

Note

This checks the options database, creates the viewer on-the-fly, uses it and then destroys it. Hence it should not be called in heavily used routines, rather PetscOptionsCreateViewer() should be used to construct the viewer once which can then be utilized in the heavily used routine.

Developer Note

This cannot use PetscObjectViewFromOptions() because ISColoring is not a PetscObject
