Package org.apache.commons.io.filefilter

Class SymbolicLinkFileFilter

  • All Implemented Interfaces:
    java.io.FileFilter, java.io.FilenameFilter, java.io.Serializable, java.nio.file.FileVisitor<java.nio.file.Path>, PathFilter, PathVisitor, IOFileFilter
    public class SymbolicLinkFileFilter
extends AbstractFileFilter
implements java.io.Serializable
    This filter accepts Files that are symbolic links.

    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(SymbolicLinkFileFilter.INSTANCE);
 for (String file : files) {
     System.out.println(file);
 }

    Using NIO

     final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(SymbolicLinkFileFilter.FILE);
 //
 // 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());
