重要的是，这是一个递归定义：有时属性将映射成零或者多列。

The important thing is that this is a recursive definition: at some point the attribute will be mapped to zero or more columns.

这种查找是递归的：如果 在 prototype 内定义的实例不能找到属性或函数，它就会在其 原型中查找，依此类推。

This lookup is recursive: if the instance defined in prototype cannot find an attribute or function, it will look in its prototype, and so on.

接下来，您会看到如何创建一个定制组件来为它的所有嵌套组件设置styleclass属性，递归遍历jsf组件树。

Next, you'll see how to create a custom component that sets the styleClass attribute for all its nested components, traversing the JSF component tree recursively.
