Detailed Description

template<>
struct lsst::afw::table::FieldBase< Flag >

Specialization for Flag fields.

Flag fields are handled specially in many places, because their keys have both an offset into an integer element and the bit in that element; while other fields have one or more elements per field, Flags have multiple fields per element. This means we can't put all the custom code for Flag in FieldBase, and because Flags have an explicit Key specialization, we put the record access implementation in Key.
