Detailed Description

template<typename COL_TYPE, typename INDEX_TYPE, template< typename > class BUFFER_TYPE>
class LvArray::SparsityPatternView< COL_TYPE, INDEX_TYPE, BUFFER_TYPE >

This class provides a view into a compressed row storage sparsity pattern.

Template Parameters

COL_TYPE	the integer used to enumerate the columns.
INDEX_TYPE	the integer to use for indexing.

When INDEX_TYPE is const m_offsets is not copied between memory spaces. INDEX_TYPE should always be const since SparsityPatternView is not allowed to modify the offsets.

When COL_TYPE is const and INDEX_TYPE is const you cannot insert or remove from the View and neither the offsets, sizes, or columns are copied between memory spaces.
