CppUtils::Thread::SharedLocker<class T>

Monitor Object wrapper providing shared read / exclusive write synchronization.

Description

Encapsulates a resource with a std::shared_mutex, allowing either multiple concurrent read-only accessors (via sharedAccess()) or a single exclusive read-write accessor (via uniqueAccess()).

constexpr SharedLocker::SharedLocker(SharedLocker&& other) noexcept(std::is_nothrow_move_constructible_v<T>);

Move constructor. Acquires lock on the source locker before moving its value.

---

constexpr auto SharedLocker::operator=(SharedLocker&& other) noexcept(std::is_nothrow_move_assignable_v<T>) -> SharedLocker&;

Move assignment. Acquires scoped lock on both mutexes before moving the value.

[[nodiscard]] constexpr auto SharedLocker::uniqueAccess() -> UniqueAccessor;

Acquires exclusive read/write access.

Retourne : UniqueAccessor holding a unique lock.

---

[[nodiscard]] constexpr auto SharedLocker::sharedAccess() const -> SharedAccessor;

Acquires shared read-only access.

Retourne : SharedAccessor holding a shared lock.
