Package org.apache.commons.io.filefilter

Class FileFileFilter

  • All Implemented Interfaces:
    FileFilter, FilenameFilter, Serializable, FileVisitor<Path>, PathFilter, PathVisitor, IOFileFilter
    public class FileFileFilter
extends AbstractFileFilter
implements Serializable
    This filter accepts Files that are files (not directories).

    For example, here is how to print out a list of the real files within the current directory:

    Using Classic IO

     File dir = new File(".");
 String[] files = dir.list(FileFileFilter.INSTANCE);
 for (String file : files) {
     System.out.println(file);
 }

    Using NIO

     final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(FileFileFilter.INSTANCE);
 //
 // Walk one dir
 Files.walkFileTree(dir, Collections.emptySet(), 1, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getFileList());
 //
 visitor.getPathCounters().reset();
 //
 // Walk dir tree
 Files.walkFileTree(dir, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getDirList());
 System.out.println(visitor.getFileList());
