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>

The internal array type.

const_reference

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::const_reference = fcppt::container::bitfield::proxy<array_type const>

A type denoting a const reference to a mask value (a reference to a boolean, basically).

Note that this is not a bool nor an internal_type, but a proxy class.

element_type

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::element_type = ElementType

Typedef to ElementType.

initializer_list_type

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::initializer_list_type = std::initializer_list<ElementType>

Initializer list type used to initialize a bitfield.

internal_type

template<typename ElementType , typename InternalType >

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

Typedef to the internal storage type (template parameter InternalType

reference

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::reference = fcppt::container::bitfield::proxy<array_type>

A type denoting a reference to a mask value (a reference to a boolean, basically).

Note that this is not a bool nor an internal_type, but a proxy class.

size_type

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::size_type = typename static_size::value_type

The size type which is taken from static_size.

value_type

template<typename ElementType , typename InternalType >

using fcppt::container::bitfield::object< ElementType, InternalType >::value_type = fcppt::container::bitfield::value_type
