FilterList is a List which can be Filtered (sorry I could'nt resist!).

FilterList there in order to wrap an arraylist containg live data and only
allow certain operations on the live data based on the Filter.

All of the Filters required for normal JDOM operation have already been
written.

As for where you would you them, normally never. Unless you have a special
requirement.
