Detailed Description

Interface of a thread-safe notification with a single asynchronous listener.

Code that must not depend on the poller type holds an INotifier. The concrete implementation is TNotifier.

Member Function Documentation

Notify()

virtual void NNet::INotifier::Notify ( )

pure virtual

Signals the listener from any thread.

Only the first call writes to the wakeup descriptor until the listener consumes the signal. A notification sent before Wait() is retained.

Implemented in NNet::TNotifier< TPoller >.

Wait()

virtual TFuture< void > NNet::INotifier::Wait ( )

pure virtual

Asynchronously waits for and consumes a notification.

Call on the poller thread, with at most one outstanding wait. The caller must check all available work after waking because notifications coalesce. Destroying an unfinished future cancels its wait on the poller thread.

Exceptions

std::logic_error

if another wait is already outstanding.

Implemented in NNet::TNotifier< TPoller >.
