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 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.
