这会创建一个匿名函数并返回此函数。

This creates an anonymous function and returns it.

由于它是在另外一个函数当中实现了一个匿名函数，人们就能够做一些前置检查和在迭代器创建之后进行计算。

Since it is implemented as an anonymous function within another function, one could do some preliminary checks and calculations before creating the iterator.

惟一需要以这种方式使用一个类的是一个默认构造函数（它允许您创建继承自类的一个匿名内部类）。

The only thing a class needs to be used this way is a default constructor (which allows you to create an anonymous inner class instance inheriting from your class).
