public class NumberRangesFileFilter extends Object implements FileFilter
This filter can select multiple discontinuous ranges based on a format similar to page selection ranges in various formatting software, such as "34,52-65,67,93-95". The constructor takes a String of this sort and deconstructs it into a list of ranges. The accepted syntax is:
ranges = range
ranges = range "," ranges
range = integer
range = integer "-" integer
Whitespace will be ignored. If the filter constructor is passed anything
that is not a list of numeric ranges of this sort, including being passed
an empty String, then an
IllegalArgumentException will be
