Package 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,- FileVisitor<Path>,- PathMatcher,- PathFilter,- PathVisitor,- IOFileFilter
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.

Serialization is deprecated and will be removed in 3.0.
