dpp::timed_listener< attached_event, listening_function > Class Template Reference

A timed_listener is a way to temporarily attach to an event for a specific timeframe, then detach when complete. A lambda may also be optionally called when the timeout is reached. Destructing the timed_listener detaches any attached event listeners, and cancels any created timers, but does not call any timeout lambda. More...

Detailed Description

template<typename attached_event, class listening_function>
class dpp::timed_listener< attached_event, listening_function >

A timed_listener is a way to temporarily attach to an event for a specific timeframe, then detach when complete. A lambda may also be optionally called when the timeout is reached. Destructing the timed_listener detaches any attached event listeners, and cancels any created timers, but does not call any timeout lambda.

Template Parameters

attached_event	Event within cluster to attach to within the cluster::dispatch member (dpp::dispatcher object)
listening_function	Definition of lambda function that matches up with the attached_event.

Constructor & Destructor Documentation

timed_listener()

template<typename attached_event , class listening_function >

dpp::timed_listener< attached_event, listening_function >::timed_listener ( cluster *  cl, uint64_t  _duration, attached_event &  event, listening_function  listener, timer_callback_t  on_end = {}  )

inline

Construct a new timed listener object.

Parameters

cl	Owning cluster
_duration	Duration of timed event in seconds
event	Event to hook, e.g. cluster.on_message_create
on_end	An optional void() lambda to trigger when the timed_listener times out. Calling the destructor before the timeout is reached does not call this lambda.
listener	Lambda to receive events. Type must match up properly with that passed into the 'event' parameter.

~timed_listener()

template<typename attached_event , class listening_function >

dpp::timed_listener< attached_event, listening_function >::~timed_listener ( )

inline

Destroy the timed listener object.
