fcppt::container::bitfield::object< ElementType, InternalType > Class Template Reference

Detailed Description

template<typename ElementType, typename InternalType>
class fcppt::container::bitfield::object< ElementType, InternalType >

Member Typedef Documentation

array_size

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::array_size = fcppt::array::size<array_type>

The size of the underlying array.

array_type

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::array_type = fcppt::container::bitfield::array<static_size, internal_type>
