PetscObjectStateSet#
Sets the state of any PetscObject
, regardless of the type.
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscObjectStateSet(PetscObject obj, PetscObjectState state)
Logically Collective
Input Parameters#
obj - any PETSc object, for example a
Vec
,Mat
orKSP
. This must be cast with a (PetscObject
), for example,PetscObjectStateSet
((PetscObject
)mat,state);state - the object state
Note#
This function should be used with extreme caution. There is
essentially only one use for it: if the user calls Mat
(Vec
)GetRow(Array),
which increases the state, but does not alter the data, then this
routine can be used to reset the state. Such a reset must be collective.
