Class Documentation

class GraphicsDomainOwner

Declaration: final

Backend lifecycle authority for a token, independent of notification routing.

Construct before native effects; allocation or identity exhaustion throws. Serialize mutations on the native owner. Destruction invalidates a still-live domain as Abandoned without callbacks or native calls.

GraphicsDomainOwner()

~GraphicsDomainOwner()

GraphicsDomainOwner(const GraphicsDomainOwner&) = delete

GraphicsDomainOwner &operator=(const GraphicsDomainOwner&) = delete

inline GraphicsDomain token() const noexcept

Declaration: [[nodiscard]]

Retain observation state independently of this backend authority and its context.

void make_available() noexcept

Commit initialization once, after mandatory native setup succeeds.

Later calls have no effect; a terminal domain cannot reopen. Performs no notification.

void shutdown() noexcept

Permanently invalidate an available domain after actual native deletion, without callbacks.

An uninitialized or already terminal domain is unchanged.

void abandon() noexcept

Permanently invalidate an available domain without native calls or callbacks.

Use when native cleanup cannot run; preserve an already committed Shutdown reason.
