Class CanWriteFileFilter

  • All Implemented Interfaces:
    FileFilter, FilenameFilter, Serializable, IOFileFilter


    public class CanWriteFileFilterextends AbstractFileFilterimplements 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:

     File dir = new File("."); String[] files = dir.list( CanWriteFileFilter.CAN_WRITE ); for ( int i = 0; i < files.length; i++ ) {     System.out.println(files[i]); } 

    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 ( int i = 0; i < files.length; i++ ) {     System.out.println(files[i]); } 

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