java.lang.Object

org.apache.commons.io.filefilter.AbstractFileFilter

org.apache.commons.io.filefilter.CanExecuteFileFilter

All Implemented Interfaces:

FileFilter, FilenameFilter, Serializable, 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:

 File dir = new File(".");
 String[] files = dir.list( CanExecuteFileFilter.CAN_EXECUTE );
 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-executable files:

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