## org.apache.commons.io.filefilter
Class CanWriteFileFilter

    java.lang.Object
      org.apache.commons.io.filefilter.AbstractFileFilter
          org.apache.commons.io.filefilter.CanWriteFileFilter

All Implemented Interfaces:
  FileFilter, FilenameFilter, Serializable, IOFileFilter

    public class CanWriteFileFilter

extends AbstractFileFilter
implements Serializable

This filter accepts `File`s 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`.
