## Rich functions
-All transformations that take as argument a lambda function can
-instead take as argument a *rich* function. For example, instead of

{% highlight scala %}
data.map { x => x.toInt }

{% highlight scala %}
class MyMapFunction extends RichMapFunction[String, Int] {

-and pass the function to a `map` transformation:
+并将函数传递给 `map` transformation:
{% highlight scala %}
data.map(new MyMapFunction())
{% endhighlight %}
-Rich functions can also be defined as an anonymous class:
+富函数也可以定义成匿名类:
Review comment:
yes，it's should be resvered as `function`

@klion26 sorry for my negligence,I see the error this time,but what i
curious is that why the link can still jump to target page.

These link-tags can be linked to correct pages,so i think it's
unnecessary to change.
