Class HiddenFileFilter

java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.HiddenFileFilter
All Implemented Interfaces:
FileFilter, FilenameFilter, Serializable, FileVisitor<Path>, PathMatcher, PathFilter, PathVisitor, IOFileFilter
public class HiddenFileFilter extends AbstractFileFilter implements Serializable
This filter accepts Files that are hidden.

Example, showing how to print out a list of the current directory's hidden files:

Using Classic IO

File dir = FileUtils.current();
String[] files = dir.list(HiddenFileFilter.HIDDEN);
for (String file : files) {
    System.out.println(file);
}

Example, showing how to print out a list of the current directory's visible (not hidden) files: 

File dir = FileUtils.current();
String[] files = dir.list(HiddenFileFilter.VISIBLE);
for (String file : files) {
    System.out.println(file);
}

Using NIO

final Path dir = PathUtils.current();
final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(HiddenFileFilter.HIDDEN);
//
// Walk one directory
Files.walkFileTree(dir, Collections.emptySet(), 1, visitor);
System.out.println(visitor.getPathCounters());
System.out.println(visitor.getFileList());
//
visitor.getPathCounters().reset();
//
// Walk directory tree
Files.walkFileTree(dir, visitor);
System.out.println(visitor.getPathCounters());
System.out.println(visitor.getDirList());
System.out.println(visitor.getFileList());
