PetscObjectListRemoveReference
Calls PetscObjectDereference() on an object in the list immediately but keeps a pointer to the object in the list.
Synopsis
PetscErrorCode PetscObjectListRemoveReference(PetscObjectList *fl,const char name[])
Input Parameters
| fl | - the object list
|
| name | - the name to use for the object
|
Notes
Use PetscObjectListAdd(PetscObjectList,const char name[],NULL) to truly remove the object from the list
Use this routine ONLY if you know that the object referenced will remain in existence until the pointing object is destroyed
Developer Note: this is to handle some cases that otherwise would result in having circular references so reference counts never got to zero
