FileArrayProvider?

On this site (http://stackoverflow.com/questions/2...-into-an-array). A person has code for a construct of FileArrayProvider. I was wondering if it is psedo-code, becaues I did a Ctrl+F search of the API page here (http://download.oracle.com/javase/7/...s-noframe.html), and found no such class. It could just be another class he created himself, but I just was wondering if anyone here has heard of it.

If you look at the first comment, the FileArrayProvider is the class he is creating as an example. Look at the package it exists in (com.acme), that should tell you right away that it is not contained in the Java libraries.
