route()

template<typename _RawEvent, typename _Handler = void>

template<bool _CleanEvent = true>

void qb::router::semh< _RawEvent, _Handler >::route ( _RawEvent & event )

Template Parameters

_CleanEvent

Whether to clean up the event after routing

Parameters

event

The event to route

subscribe()

template<typename _RawEvent, typename _Handler = void>

void qb::router::semh< _RawEvent, _Handler >::subscribe ( _Handler & handler )

inlinenoexcept

Subscribe a handler to receive events.

Parameters

handler

The handler to subscribe

unsubscribe()

template<typename _RawEvent, typename _Handler = void>

void qb::router::semh< _RawEvent, _Handler >::unsubscribe ( _HandlerId const & id )

Parameters
