> I'm attaching a patch which extracts the FileFilter implementations out of the FindingFilter class into a separate "filters" package. This will allow them to be re-used in conjunction with a new CompositeFilter.
> I've created a new CompositeFilter implementation (which FindingFilter is now based on) which can do AND or OR processing which I think will allow quite powerful FileFilter implementations to be created - since CompositeFilters themselves can be used as component FileFilters for more complex CompositeFilters.
> For example to select files which are less than 1MB and have been modified in the last 20 days
> CompositeFilter filter1 = new CompositeFilter(false, true);
> filter1.addFilter(new SizeFilter(false, "-1m"));
> filter1.addFilter(new TimeFilter(false, 20, false));
> As a by-product IMO it will also make creating test cases for the individual FileFilter implementations easier.
