-In this example, we build the class `StringLength`, which has two methods: a `factory` method and an `strlen` method.  Stricly speaking, the only method that a UDF requires is a `factory` method, which returns another method (in this case `strlen`) that performs the actual computation.  The only requirement for the UDF computation method is that its first argument be `tuple_data`, a dictionary of data that is returned with all tweets (read more about this --This link is missing.[here](http://mehack.com/map-of-a-twitter-status-object)).

 You can include any number of arguments after `tuple_data`.  In our case, we only take one: the string `val` which we wish to take the length of.  Note that when we run the query on the last line of this example, we pass `text` as an argument to `stringlength`---this is the value that `val` will take on.
