event-controller v1.0.1

SYNOPSIS

Simple JavaScript event controller implementation. Similar to Node.js EventEmitter, but manages a single event type.

• Useful for building interfaces that favor composition over inheritance. Event controllers could be assigned to instance properties instead of using inherited EventEmitter.
• Manages a single event, avoids extra event type lookup. Can't dispatch arbitrary events, each event type needs its own controller.
• Doesn't rely on strings to identify event types.
• Might be faster (see benchmark below).

USAGE

var EventController = require('event-controller');
var event1 = new EventController();

// Add listener
event1.add(function (value) {
  // handle event
});

// Dispatch
event1.dispatch('hello');

Interface example:

function MyObject() {
  this.onError = new EventController();
  this.onReceive = new EventController();
}

var obj = new MyObject();

// Add error handler
obj.onError.add(function() {});

// Dispatch error
obj.onError.dispatch(new Error());

##API

###.add(fn)

Add new event listener.

###.remove(fn)

Remove event listener.

###.dispatch(args...) .raise(args...)

Dispatch new event.

##BENCHMARK

Random benchmark results for 1 event type and 2 listeners .

EventEmitter x 1,269,447 ops/sec ±3.63% (85 runs sampled)
EventController x 3,427,809 ops/sec ±2.19% (88 runs sampled)
Fastest is EventController
