How to use ---------- [](#how-to-use) ``` // we need event provider to add events to that $event_provider = new EventProvider(); // also we need closure provider to add closures to that $closure_provider = new ClosureProvider(); // then use their methods $event_provider->addEvent(new Event('boot')) ->addEvent(new Event('close')); //----- $closure_provider->addClosure($nameOfClosureOrKey, function () { // define closure functionality }); // to instanciate an emitter object, // use event provider and closure provider, // from above $emitter = new Emitter($event_provider, $closure_provider); // now work with listeners $emitter->addListener($nameOfEvent, $nameOfClosureOrKey); $emitter->removeListener($nameOfEvent, $nameOfClosureOrKey); // finally dispatch event where you want $emitter->dispatch($nameOfEvent); ``` Available functions ------------------- [](#available-functions) #### EventProvider [](#eventprovider) - addEvent(IEvent $event): IEventProvider This method add an event to the provider ``` // to add an event $event_provider->addEvent(new Event('cartOnBoot')); ``` - removeEvent(string $event\_name): IEventProvider This method remove an event from the provider ``` // to remove an event $event_provider->removeEvent('cartOnBoot'); ``` - getEvent(string $event\_name): IEvent This method gets an event from the provider ``` // to get an event $event_provider->getEvent('cartOnBoot'); ``` - hasEvent(string $event\_name): bool This method checks to see if an event is exist in provider ``` // check if an event exists $event_provider->hasEvent('cartOnBoot'); ``` #### ClosureProvider [](#closureprovider) - addClosure($key, $closure): IClosureProvider This method add a closure to provider ``` // to add a closure $closure_provider->addClosure($closureKeyOrName, function () { // define closure functionality }); ``` - removeClosure($key): IClosureProvider This method removes a closure from provider ``` // to remove a closure $closure_provider->removeClosure($closureKeyOrName); ``` - getClosure($key): Closure This method gets a closure from provider ``` // to get a closure $closure_provider->getClosure($closureKeyOrName); ``` - hasClosure($key): bool This method checks to see if a closure is exist in provider ``` // check if a closure exists $closure_provider->hasClosure('cartOnBoot'); ``` #### Emitter [](#emitter) - addListener(string $event\_name, string $closure\_name, int $priority = 0): IEmitter This method add a listener to emitter Note: If you need some listeners to emit faster than others, then you should pass priority as a number.(Higher value means higher priority) ``` // to add a listener $emitter->addListener('cartOnBoot', 'cart_boot'); // or with a higher priority $emitter->addListener('cartOnBoot', 'cart_boot', 5); ``` - removeListener(string $event\_name, string $closure\_name): IEmitter This method removes a listener from emitter ``` // to remove a listener $emitter->removeListener('cartOnBoot', 'cart_boot'); ``` - removeAllListeners(string $event\_name): IEmitter This method remove all listeners of an event from emitter **Note:** Now you can pass wild cards *(regex)* as event too! ``` // to remove a listener $emitter->removeAllListeners('cartOnBoot'); // to remove a listener with wild card // // code below will find all events like // [cart:boot], [cartOnBoot], etc. // and remove them all $emitter->removeAllListeners('cart:?.*'); ``` - getListener(string $event\_name): array This method gets all listeners of an event from emitter ``` // to get all listeners of an event $emitter->getListener('cartOnBoot'); ``` - getAllListeners($wild\_card = null): array This method gets all listeners from emitter **Note:** You can filter listeners with their events through an extra parameter *$wild\_card* that is a regex ``` // to get all listeners $emitter->getAllListeners(); // to get all events with [cart:boot] and [cart:orders] $emitter->getAllListeners('cart:(boot|orders)'); ``` License ======= [](#license) Under MIT license. ### Health Score 26 — LowBetter than 43% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity9 Limited adoption so far Community9 Small or concentrated contributor base Maturity55 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
