• on
• once
• removeAllListeners
• removeAllOnceListeners
• removeOnceListener
• removeOnceListener

NOTE: Overwrites the following variables within the instance of a class

Loading

index.js is the source code and is compatible with browserify. index.umd.js was built as a standalone UMD package (without minification) so you can use it with AMD or a normal browser environment... The exported global is the name of the package within package.json (with hyphens etc removed).

Example

var MyClass = function() {
};

MyClass.prototype.doSomething = function() {
	return this._emit('doneit','a','b');
};

addEvents(MyClass,['doneit']);

var myClass = new MyClass();
myClass.on('doneit',function (a, b) {
	console.log('a = ' + a + ', b = ' + b);
});

myClass.doSomething();

Parameters

• @param {Function} classFunc The class to add events to.
• @param {Array} events The events you want the class to support.
