Class CanExecuteFileFilter

java.lang.Object
org.apache.commons.io.filefilter.AbstractFileFilter
org.apache.commons.io.filefilter.CanExecuteFileFilter
All Implemented Interfaces:
FileFilter, FilenameFilter, Serializable, FileVisitor<Path>, PathMatcher, PathFilter, PathVisitor, IOFileFilter
public class CanExecuteFileFilter extends AbstractFileFilter implements Serializable
This filter accepts Files that can be executed.

Example, showing how to print out a list of the current directory's executable files:

Using Classic IO

 File dir = FileUtils.current();
 String[] files = dir.list(CanExecuteFileFilter.CAN_EXECUTE);
 for (String file : files) {
     System.out.println(file);
 }

Example, showing how to print out a list of the current directory's non-executable files: 

 File dir = FileUtils.current();
 String[] files = dir.list(CanExecuteFileFilter.CANNOT_EXECUTE);
 for (int i = 0; i < files.length; i++) {
     System.out.println(files[i]);
 }
