Detailed Description

An event handler.

It provides a simple way to inherits several times from Observer and cutomize event receiving method name.

Constructor & Destructor Documentation

template<typename Event , typename Derived >

anch::events::EventHandler< Event, Derived >::EventHandler	(	const std::function< void(Derived &, const Event &) noexcept > &	callbackFunction,
		bool	useEventBus = `false`
	)

inline

EventHandler constructor.
Register callback method.
Register itself in global EventBus if set.

Parameters

callbackFunction	the callback method to use on notify
useEventBus	if `true` register itself in global EventBus, `false` otherwise (default)

template<typename Event , typename Derived >

anch::events::EventHandler< Event, Derived >::EventHandler	(	const std::function< void(Derived &, const Event &) noexcept > &	callbackFunction,
		anch::events::EventBus< Event > &	eventBus
	)

inline

EventHandler constructor.
Registers callback method.
Register itself in EventBus.

Parameters

callbackFunction	the callback method to use on notify
eventBus	the EventBus to register itself

template<typename Event , typename Derived >

virtual anch::events::EventHandler< Event, Derived >::~EventHandler ( )

inlinevirtual

EventHandler destructor.
Unregister EventHandler from EventBus if needed.

template<typename Event , typename Derived >

virtual void anch::events::EventHandler< Event, Derived >::notify ( const Event & event )

inlinevirtualnoexcept

Invokes callback method on receiving event.

Parameters

event the event which has been fired
