fabriceleal / EventEmitter.once.js
Created September 4, 2012 23:08
node.js EventEmitter.once (with example) (answer for http://stackoverflow.com/questions/12150540/javascript-eventemitter-multiple-events-once)
// "Extend" the EventEmitter like this:
var EventEmitter = require('events').EventEmitter;
EventEmitter.prototype.once = function(events, handler){
// no events, get out!
if(! events)
return;
// Ugly, but helps getting the rest of the function
