Constructor & Destructor Documentation

template<typename Storage>

constexpr util::flags::Flag_t< Storage >::Flag_t ( Index_t flagIndex )

inline

Constructs from the flag index.

Definition at line 95 of file BitMask.h.

95 : bits(details::makeBits<Storage_t>(flagIndex)) {}

util::flags::Flag_t::bits

Storage_t bits

The bits representing this flag (only one is set)

Definition: BitMask.h:92

Member Function Documentation

template<typename Storage>

constexpr Flag_t util::flags::Flag_t< Storage >::copy ( ) const

inline

Returns a copy of this object.

Returns: a copy of this flag

When a flag is declared as constexpr, functions trying to take its address will trigger a link failure (as there is no address for a constexpr). Passing a copy of it should fix the problem.

template<typename Storage>

constexpr Index_t util::flags::Flag_t< Storage >::index ( ) const

Returns the index of the (first) bit set.
