public class NameFileFilter extends AbstractFileFilter implements Serializable
Filters file names for a certain name.

For example, to print all files and directories in the current directory whose name is Test:

Using Classic IO

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

Using NIO

 final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(new NameFileFilter("Test"));
 //
 // 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());

      public NameFileFilter(String name)
      Constructs a new case-sensitive name file filter for a single name.

      public NameFileFilter(String... names)
      Constructs a new case-sensitive name file filter for an array of names.

      The array is not cloned, so could be changed after constructing the instance. This would be inadvisable however.

      ??:
      IllegalArgumentException - if the names array is null
