Detailed Description

template<typename VECTOR>
class geosx::BlockVectorView< VECTOR >

Abstract view of a block vector.

Template Parameters

VECTOR type of sub-vectors

This class does not deal with constructing or storing sub-vectors, only provides high-level access functions. See derived classes BlockVector and BlockVectorWrapper for ways to construct a block vector.
