Class CanWriteFileFilter

java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.CanWriteFileFilter
All Implemented Interfaces:
FileFilter, FilenameFilter, Serializable, FileVisitor<Path>, PathMatcher, PathFilter, PathVisitor, 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:

Using Classic IO

 File dir = FileUtils.current();
 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 = FileUtils.current();
 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.
