pomelo组件..

1.pomelo会加载lib/components目录下的组件.并设置为属性..和存储在Pomelo.components中..注意这里其实存储的是对象的构造函数..

 function load() {
    return require('./components/' + name);
  }
  Pomelo.components.__defineGetter__(name, load);
  Pomelo.__defineGetter__(name, load);

2.当app.start的时候..会加载默认组件:master和monitor组件

app.load(pomelo.master, app.get('masterConfig'));  //从这里可以看到..可以将配置提前赋值到app中

3.Application.load   加载组件..会把组件存储到app中的load和component中..  注意这里的组件是组件实例化后的对象了

if(typeof component === 'function') { 
      component = component(this, opts);
   }

......

this.loaded.push(component);
  if(name) {
    // components with a name would get by name throught app.components later.
    this.components[name] = component;
  }
