# delegate
Creates delegate functions automatically. This is useful if you don't want to use util.inherits.
## Example
Simple example.
```javascript
var A = function() {
this.evtEmitter = new delegate.EventEmitter();
delegate(this, this.evtEmitter);
};
var obj = new A();
obj.on("test", function (data) {
// read data
});
```
Example using class.js module.
```javascript
var delegate = require('delegate');
var Class = require('class.js');
var MyEventEmitter = function () {
events.EventEmitter.call(this);
};
util.inherits(MyEventEmitter, events.EventEmitter);
var A = Class({
init: function () {
this.evtEmitter = new MyEventEmitter();
delegate(this, this.evtEmitter);
}
});
var B = A.extend({
emitDataEvent: function () {
this.emit("data", 'hello world');
}
});
var obj = new B();
obj.on("test", function (data) {
// read data
});
```
