Constructor & Destructor Documentation

notifier()

template<typename Result , typename... Args>

constexpr v1::notifier< Result(Args...)>::notifier ( )

constexprdefaultnoexcept

Create a notifier.

Member Function Documentation

operator co_await()

template<typename Result , typename... Args>

awaiter_type v1::notifier< Result(Args...)>::operator co_await ( ) const

inlinenoexcept

Create an awaiter that can await on this notifier.

operator()()

template<typename Result , typename... Args>

void v1::notifier< Result(Args...)>::operator() ( Args const &... args ) const

inlinenoexcept

Call the subscribed callbacks with the given arguments.

Note

This function is not reentrant.

Parameters

args	The arguments to pass with the invocation of the callback

subscribe()

template<typename Result , typename... Args>

callback_token v1::notifier< Result(Args...)>::subscribe ( forward_of< callback_proto > auto && callback, callback_flags flags = callback_flags::synchronous )

inlinenoexcept

Add a callback to the notifier.

Ownership of the callback belongs with the caller of subscribe(). The caller will receive a token, a move-only RAII object that will unsubscribe the callback when the token is destroyed.

Parameters

flags	The callback-flags used to determine how the callback is called.
callback	A function object to call when being notified.

Returns

A RAII object which when destroyed will unsubscribe the callback.
