# PetscObjectViewSAWs
View the base portion of any object with an SAWs viewer 
## Synopsis
```
#include "petscsys.h"  */
PetscErrorCode PetscObjectViewSAWs(PetscObject obj, PetscViewer viewer)
```
Collective


## Input Parameters

- ***obj -*** the `PetscObject` variable. Thus must be cast with a (`PetscObject`), for example, `PetscObjectSetName`((`PetscObject`)mat,name);
- ***viewer -*** the SAWs viewer





## Note
The object must have already been named before calling this routine since naming an
object can be collective.


## Developer Note
Currently this is called only on MPI rank 0 of `PETSC_COMM_WORLD`


## See Also

## Level
