ISRegister#

Adds a new index set implementation

Synopsis#

#include "petscis.h"  
PetscErrorCode ISRegister(const char sname[], PetscErrorCode (*function)(IS))

Not Collective

Input Parameters#

  • sname - The name of a new user-defined creation routine

  • function - The creation routine itself

Sample usage#

    ISRegister("my_is_name",  MyISCreate);

Then, your vector type can be chosen with the procedural interface via

    ISCreate(MPI_Comm, IS *);
    ISSetType(IS,"my_is_name");

or at runtime via the option

    -is_type my_is_name

Notes#

ISRegister() may be called multiple times to add several user-defined vectors

This is no ISSetFromOptions() and the current implementations do not have a way to dynamically determine type, so dynamic registration of custom IS types will be of limited use to users.
