public class WildcardOSFilter extends org.apache.commons.io.filefilter.AbstractFileFilter
Filters files using supplied wildcard(s). Based on the Apache WildcardFilter class in the Commons IO package. Difference is that in this class, it uses the org.apache.commons.io.FilenameUtils.wildcardMatchOnSystem() for its matching rules, which means that pattern matching using this class is OS dependent (case-insensitive on Windows and case-sensitive on Unix, Linux, MAC)- Version:
