| 24 | * CommandHandler for the LIST command. Return the configured directory listing on the data
|
| 25 | * connection, along with two replies on the control connection: a reply code of 150 and
|
| 26 | * another of 226. By default, return an empty directory listing. You can customize the
|
| 27 | * returned directory listing by setting the <code>directoryListing</code> property.
|
| 28 | * <p/>
|
| 29 | * The interpretation of the value returned from this command is dependent upon the value returned
|
| 30 | * by the SYST command. The format of the directory listing should match the format associated with
|
| 31 | * the system named by the SYST command. For example, if the SYST command returns "WINDOWS", then
|
| 32 | * the directory listing value from this command should match the Windows-specific format. See the
|
| 33 | * <code>SystCommandHandler</code> to control the value returned for the SYST command.
|
| 34 | * <p/>
|
| 35 | * Here is an example value for <code>directoryListing</code> when the <code>SystCommandHandler</code>
|
| 36 | * returns "WINDOWS". Note that multiple entries are separated by "\n":
|
| 37 | * <code><pre>
|
| 38 | * CommandHandler listCommandHandler = new ListCommandHandler();
|
| 39 | * listCommandHandler.setDirectoryListing("11-09-01 12:30PM 406348 File2350.log\n" +
|
| 40 | * "11-01-01 1:30PM <DIR> archive");
|
| 41 | * </pre></code>
|
| 42 | * <p/>
|
| 43 | * And here is an example value for <code>directoryListing</code> when the <code>SystCommandHandler</code>
|
| 44 | * returns "UNIX". Note that multiple entries are separated by "\n":
|
| 45 | * <code><pre>
|
| 46 | * CommandHandler listCommandHandler = new ListCommandHandler();
|
| 47 | * listCommandHandler.setDirectoryListing("drwxrwxrwx 1 none none 0 Mar 20 2010 archive\n" +
|
| 48 | * "-rwxrwxrwx 1 none none 19 Mar 20 2010 abc.txt");
|
| 49 | * </pre></code>
|
| 50 | * <p/>
|
| 51 | * Each invocation record stored by this CommandHandler includes the following data element key/values:
|
| 52 | * <ul>
|
| 53 | * <li>{@link #PATHNAME_KEY} ("pathname") - the pathname of the directory (or file) submitted on the
|
| 54 | * invocation (the first command parameter); this parameter is optional, so the value may be null.
