Detailed Description

A packed representation of a collection of Flag field columns.

The packing of bits here is not necessarily the same as the packing using in the actual table, as the latter may contain more than 64 bits spread across multiple integers.

A BitsColumn can only be constructed by calling BaseColumnView::getBits().
