Member Function Documentation

void sc::SCVector::assign (SCVector * v) [inline]

Make this have the same elements as v. The dimensions must match.

virtual void sc::SCVector::convert (SCVector *) [virtual]

Convert an SCVector of a different specialization to this specialization and possibly accumulate the data.

virtual Ref<SCMatrixSubblockIter> sc::SCVector::local_blocks (SCMatrixSubblockIter::Access) [pure virtual]

Returns iterators for the local (rapidly accessible) blocks used in this vector. Only one iterator is allowed for a matrix is it has Accum or Write access is allowed. Multiple Read iterators are permitted.

Implemented in sc::BlockedSCVector, sc::DistSCVector, sc::LocalSCVector, and sc::ReplSCVector.
