Detailed Description

template<typename _Derived, typename _EV_EVENT>
class qb::io::async::base< _Derived, _EV_EVENT >

Base class for all qb-io asynchronous components that interact with the event listener.

This template class provides the foundational mechanism for registering and unregistering a specific libev event watcher (represented by _EV_EVENT) with the thread-local qb::io::async::listener::current. Derived classes (using CRTP via _Derived) will typically inherit from this to manage their primary event watcher.

Template Parameters

_Derived	The derived class type (CRTP pattern).
_EV_EVENT	The specific qb::io::async::event::* type (which wraps a libev watcher, e.g., event::io, event::timer).

Constructor & Destructor Documentation

base()

template<typename _Derived, typename _EV_EVENT>

qb::io::async::base< _Derived, _EV_EVENT >::base ( )

inlineprotected

Constructor that registers the event watcher with the current listener.

The _async_event member is initialized by calling listener::current.registerEvent, associating the derived class instance (Derived) as the handler for this event type.

~base()

template<typename _Derived, typename _EV_EVENT>

qb::io::async::base< _Derived, _EV_EVENT >::~base ( )

inlineprotected

Destructor that unregisters the event watcher.

Stops the event watcher and unregisters it from the listener to prevent dangling references and ensure proper cleanup of libev resources. Specifically, it calls _async_event.stop() and then listener::current.unregisterEvent(_async_event._interface).
