#include "petsc/private/petscimpl.h" PetscErrorCode PetscObjectStateIncrease(PetscObject obj)Logically Collective Many br
Notes: object state is an integer which gets increased every time Many brthe object is changed internally. By saving and later querying the object state Many brone can determine whether information about the object is still current. Many brCurrently, state is maintained for Vec and Mat objects. Many br
This routine is mostly for internal use by PETSc; a developer need only Many brcall it after explicit access to an object's internals. Routines such Many bras VecSet() or MatScale() already call this routine. It is also called, as a Many brprecaution, in VecRestoreArray(), MatRestoreRow(), MatDenseRestoreArray(). Many br
This routine is logically collective because state equality comparison needs to be possible without communication. Many br
