org.apache.commons.io.filefilter.AbstractFileFilter

org.apache.commons.io.filefilter.CanWriteFileFilter

All Implemented Interfaces:

java.io.FileFilter, java.io.FilenameFilter, java.io.Serializable, 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:

 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.
