Package org.apache.commons.io.filefilter

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 Link icon

 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 Link icon

 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());
