Detailed Description

template<class ScalarType, class MV, class OP, class DM = DefaultDenseMatrix<int, ScalarType>>
class Belos::GCRODRIteration< ScalarType, MV, OP, DM >

Common base interface for GCRODRIter and FGCRODRIter.

This mirrors the role of GmresIteration for BlockGmresSolMgr. It lets GCRODRSolMgr store either the standard or flexible iterator in the same RCP variable.
