fcppt::strong_typedef< T, Tag > Class Template Reference

Detailed Description

template<typename T, typename Tag>
class fcppt::strong_typedef< T, Tag >

Used to create strong typedefs.

Template Parameters

T	The underlying type to be wrapped.
Tag	Some unique type.

A strong typedef is a wrapper around a type. It has an explicit constructor and a get member function.

Public Types
using	value_type = T
	A type that represents the data stored in the strong typedef.
using	tag_type = Tag
	typedef for the Tag template parameter

Public Member Functions
constexpr	strong_typedef (T const &) noexcept(std::is_nothrow_copy_constructible_v< T >)
	Constructs a strong typedef by copying.
constexpr	strong_typedef (T &&) noexcept(std::is_nothrow_move_constructible_v< T >)
	Constructs a strong typedef by moving.
	strong_typedef (fcppt::no_init const &)
	Creates an uninitialized strong typedef.
constexpr T &	get ()
	Return the strong typedef's value.
constexpr T const &	get () const
	Return the strong typedef's value.
