Class CanWriteFileFilter

  • 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 CanWriteFileFilter
    extends AbstractFileFilter
    implements java.io.Serializable
    This filter accepts Files that can be written to.

    Example, showing how to print out a list of the current directory's writable files:

    Using Classic IO

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

    Example, showing how to print out a list of the current directory's un-writable files:

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

    N.B. For read-only files, use CanReadFileFilter.READ_ONLY.
