deploy-event v1.0.2

deploy-event

deploy-event make it able to create a cancellable class-based events. (priority can be specified)

Introducion

deploy-event provides some features
That are not present in the EventEmitter.
An event based on a class of a particular file, and
(the listener is possible confirm the argument list)
Event listener can receive the event specified by the priority.

How to use deploy-class?

Install module and define it.

• type in terminal npm install deploy-event
• type in source file let DeployEvent = require('deploy-event');
• type * let Event = DeployEvent.Event;
• type * let EventDispatcher = DeployEvent.EventDispatcher;
• type * let EventPriority = DeployEvent.EventPriority;

Create event, create dispatcher.

• Event Inheritance can be create to the another event. create some event.
• (ex. class NotificationEvent extends Event{})
• Dispatcher dispensing the called events for the priority. create some dispatcher.
• (ex. let NotificationDispatcher = new EventDispatcher();)

Create listener.

• Dispatcher can be register listner function. create and register some process function.
• (ex. let processFunction = (eventInstance)=> {/* */})
• (ex. NotificationDispatcher.on(NotificationEvent, processFunction, EventPriority.LOW);)
• (listener will be received event instance, so it can ue it)
• (event cancel method -> eventInstance.setCancelled(boolean))
• (event cancel check method -> eventInstance.isCancelled() it will be return boolean, listener sometimes must be check event has cancelled! /not automatic cut/ )

Create eventInstance, create event call.

• If you want to use some Event, it must be makes new.
• (ex. let myEvent = new NotificationEvent();)
• Do what ever you want it eventInstance, and call the dispatcher.
• (ex. NotificationDispatcher.call(myEvent);)
• And yes, simply event will be send every listener! :P
