Hi, I'm working on implementing pycc::CRS as a direct sub class of dolfin::GenericMatrix, and need an abstract base class for sparsity patterns. For the moment, dolfin::SparsityPattern is not polymorphic, so I can't inherit from it. The best solution would perhaps be to have a GenericSparsityPattern defining the public interface for sparsity patterns, and then dolfin can implement dolfin::SparsityPattern as a concrete subclass, and in PyCC we can implement a pycc::CRSGraph as another subclass.
Any ideas or future plans for implementing this? The benefit from this construction would be the possibility of using dolfin/ffc to assemble pdes in PyCC, such that we can throw our old matrix factories out the door.
