mogwai/src/extends.js

Object-to-graph mapper for Node.js using Gremlin in Mongoose style (very alpha work)

// Inspired by CoffeeScript
module.exports = __extends = function(child, parent) {
    for (var key in parent) {
      if ({}.hasOwnProperty.call(parent, key)) {
        child[key] = parent[key];
      }
    }

    function ctor() {
      this.constructor = child;
    }

    ctor.prototype = parent.prototype;
    child.prototype = new ctor();
    child.__super__ = parent.prototype;

    return child;
  };
