All Implemented Interfaces:

FilenameFilter

public class FilenameFilterDir
extends Object
implements FilenameFilter

Simple filter to find directory entries.

This file filter can be used to find directory entries under a specific directory. The easiest way to see how to use this class is to look at the following example which prints out the directory entries under the directory specified:

import com.ccg.io.FilenameFilterDir;
import java.io.*;

class Example {
  public static void main(String[] args) {
    String dirName = ".";
    if (args.length == 1) dirName = args[0];

    File dir = new File(dirName);
    String[] dlist = dir.list(new FilenameFilterDir());
    System.out.println(dir+"  entries:"+dlist.length);
    for (int i = 0; i < dlist.length; i++) {
      System.out.println("  "+dlist[i]);
    }
  }
}
