node-forwardable

================

Ruby's forwardable inspired module which defines delegatable functionality of methods for a class.

## Install

    npm install forwardable

## Example

    var util = require('util')

      , forwardable = require('../').forwardable

      , log = console.log.bind(console);

    

    var Queue = function() {

      this.q = []; // prepare delegate object

    };

    

    util._extend(Queue, forwardable);

    

    // setup preferred interface, enq() and deq()...

    Queue.defDelegator('q', 'push', 'enq');

    Queue.defDelegator('q', 'shift', 'deq');

    

    // support some general Array methods that fit Queues well

    Queue.defDelegators('q', 'push', 'shift');

    

    var q = new Queue;

    q.enq(1, 2, 3, 4, 5);

    q.push(6);

    

    log(q.shift()); //=> 1

    while (q.q.length > 0) {

      log(q.deq());  //=> 2, 3, 4, 5, 6

    }
