Alan Gates commented on PIG-1354:
---------------------------------
+1, looks good.
In my run of the tests it looks like the overhead of the reflection is about
3x. That's reasonable for quick and dirty work, and if people want better
performance they can implement the method in a dedicated Pig Latin UDF.
One question, you have it set to do int, long, float, double, and string. Do
you ever see a need to have byte[] <-> bytearray?

> The need to create wrapper UDFs for simple Java functions creates unnecessary
> work for Pig users, slows down the development process, and produces a lot of
> trivial classes. We can use Java's reflection to allow invoking a number of
> methods on the fly, dynamically, by creating a generic UDF to accomplish this.
