I have added PetscObjectPrintClassNamePrefixType() which is now (in theory) used uniformly in all the XXXView ASCII info formats to display this information appropriately. A nice improvement, eliminated lots of duplicate code and makes it easier to have uniform output.
PetscObjects are NOT given names by default, you should call PetscObjectSetName() to give it a name. In a small number of places when an object NEEDS a name, for example when it is saved to Matlab with that variable name then PetscObjectName() is called to generate a "unique" name. Thanks for the suggestion, Barry > What does PetscObjectName() do??Generate a random name?? Currently it generates a name that looks like classname_commid_number where number is incremented sequentially. I would lean towards always naming everything so that a unique identifier is available. Unfortunately, doing so would make all the test output non-reproducible because the identifier (for generated names) includes some run-dependent information (commid above). Maybe name everything, but have an option to turn it off?
