+ * is the {@link #setDatagramSocketFactory  setDatagramSocketFactory }
+ * method, which allows you to control the type of DatagramSocket the
+ * DatagramSocketClient creates for network communications.  This is

+ * support for applets.  For
+ * example, you could create a
+ * {@link DatagramSocketFactory}
+ *  that
+ * requests browser security capabilities before creating a socket.

+ * {@link #_socketFactory_  _socketFactory_ } member variable to
+ * create DatagramSocket instances rather than instantiating
+ * them by directly invoking a constructor.  By honoring this contract

+ * is not universal.  Unfortunately, nothing in the FTP spec allows this to
+ * be determined in an automated way, so manual configuration such as this
+ * is necessary.
+ * </p><p>
+ * This functionality was designed to allow existing clients to work exactly
+ * as before without requiring use of this component.  This component should
+ * only need to be explicitly invoked by the user of this package for problem
+ * cases that previous implementations could not solve.

+ * than the American English "standard" <code>MM dd yyyy</code></li>
+ * <li>is in different timezone and you need accurate timestamps for
+ * dependency checking as in Ant</li>
+ * </ul>

+/**
+ * FTPFileEntryParser defines the interface for parsing a single FTP file
+ * listing and converting that information into an
+ * {@link FTPFile} instance.
+ * Sometimes you will want to parse unusual listing formats, in which
+ * case you would create your own implementation of FTPFileEntryParser and
+ * if necessary, subclass FTPFile.
+ * <p>
+ * Here are some examples showing how to use one of the classes that
+ * implement this interface.
+ * <p>
+ *
+ * The first example uses the <code>FTPClient.listFiles()</code>
+ * API to pull the whole list from the subfolder <code>subfolder</code> in
+ * one call, attempting to automatically detect the parser type.  This
+ * method, without a parserKey parameter, indicates that autodection should
+ * be used.
+ *
+ * <pre>
+ *    FTPClient f=FTPClient();
+ *    f.connect(server);
+ *    f.login(username, password);
+ *    FTPFile[] files = f.listFiles("subfolder");
+ * </pre>
+ *
+ * The second example uses the <code>FTPClient.listFiles()</code>
+ * API to pull the whole list from the current working directory in one call,
+ * but specifying by classname the parser to be used.  For this particular
+ * parser class, this approach is necessary since there is no way to
+ * autodetect this server type.
+ *
+ * <pre>
+ *    FTPClient f=FTPClient();
+ *    f.connect(server);
+ *    f.login(username, password);
+ *    FTPFile[] files = f.listFiles(
+ *      "org.apache.commons.net.ftp.parser.EnterpriseUnixFTPFileEntryParser",
+ *      ".");
+ * </pre>
+ *
+ * The third example uses the <code>FTPClient.listFiles()</code>
+ * API to pull a single file listing in an arbitrary directory in one call,
+ * specifying by KEY the parser to be used, in this case, VMS.
+ *
+ * <pre>
+ *    FTPClient f=FTPClient();
+ *    f.connect(server);
+ *    f.login(username, password);
+ *    FTPFile[] files = f.listFiles("VMS", "subfolder/foo.java");
+ * </pre>
+ *
+ * For an alternative approach, see the {@link FTPListParseEngine} class
+ * which provides iterative access.
+ *
+ * @version $Id: FTPFileEntryParser.java 1747119 2016-06-07 02:22:24Z ggregory $

+/**
+ * This class handles the entire process of parsing a listing of
+ * file entries from the server.
+ * <p>
+ * This object defines a two-part parsing mechanism.
+ * <p>
+ * The first part is comprised of reading the raw input into an internal
+ * list of strings.  Every item in this list corresponds to an actual
+ * file.  All extraneous matter emitted by the server will have been
+ * removed by the end of this phase.  This is accomplished in conjunction
+ * with the FTPFileEntryParser associated with this engine, by calling
+ * its methods <code>readNextEntry()</code> - which handles the issue of
+ * what delimits one entry from another, usually but not always a line
+ * feed and <code>preParse()</code> - which handles removal of
+ * extraneous matter such as the preliminary lines of a listing, removal
+ * of duplicates on versioning systems, etc.
+ * <p>
+ * The second part is composed of the actual parsing, again in conjunction
+ * with the particular parser used by this engine.  This is controlled
+ * by an iterator over the internal list of strings.  This may be done
+ * either in block mode, by calling the <code>getNext()</code> and
+ * <code>getPrevious()</code> methods to provide "paged" output of less
+ * than the whole list at one time, or by calling the
+ * <code>getFiles()</code> method to return the entire list.
+ * <p>
+ * Examples:
+ * <p>
+ * Paged access:
+ * <pre>
+ *    FTPClient f=FTPClient();
+ *    f.connect(server);
+ *    f.login(username, password);
+ *    FTPListParseEngine engine = f.initiateListParsing(directory);
+ *
+ *    while (engine.hasNext()) {
+ *       FTPFile[] files = engine.getNext(25);  // "page size" you want
+ *       //do whatever you want with these files, display them, etc.
+ *       //expensive FTPFile objects not created until needed.
+ *    }
+ * </pre>
+ * <p>
+ * For unpaged access, simply use FTPClient.listFiles().  That method
+ * uses this class transparently.

+     * Very brief and incomplete description of the zOS/MVS-filesystem. (Note:
+     * "zOS" is the operating system on the mainframe, and is the new name for
+     * MVS)
+     *
+     * The filesystem on the mainframe does not have hierarchal structure as for
+     * example the unix filesystem. For a more comprehensive description, please
+     * refer to the IBM manuals
+     *
+     * @LINK:

+     *
+     *
+     * Dataset names =============
+     *
+     * A dataset name consist of a number of qualifiers separated by '.', each
+     * qualifier can be at most 8 characters, and the total length of a dataset
+     * can be max 44 characters including the dots.
+     *
+     *
+     * Dataset organisation ====================
+     *
+     * A dataset represents a piece of storage allocated on one or more disks.
+     * The structure of the storage is described with the field dataset
+     * organinsation (DSORG). There are a number of dataset organisations, but
+     * only two are usable for FTP transfer.
+     *
+     * DSORG: PS: sequential, or flat file PO: partitioned dataset PO-E:
+     * extended partitioned dataset
+     *
+     * The PS file is just a flat file, as you would find it on the unix file
+     * system.
+     *
+     * The PO and PO-E files, can be compared to a single level directory
+     * structure. A PO file consist of a number of dataset members, or files if
+     * you will. It is possible to CD into the file, and to retrieve the
+     * individual members.
+     *
+     *
+     * Dataset record format =====================
+     *
+     * The physical layout of the dataset is described on the dataset itself.
+     * There are a number of record formats (RECFM), but just a few is relavant
+     * for the FTP transfer.
+     *
+     * Any one beginning with either F or V can safely used by FTP transfer. All
+     * others should only be used with great care, so this version will just
+     * ignore the other record formats. F means a fixed number of records per
+     * allocated storage, and V means a variable number of records.
+     *
+     *
+     * Other notes ===========
+     *
+     * The file system supports automatically backup and retrieval of datasets.
+     * If a file is backed up, the ftp LIST command will return: ARCIVE Not
+     * Direct Access Device KJ.IOP998.ERROR.PL.UNITTEST
+     *
+     *
+     * Implementation notes ====================
+     *
+     * Only datasets that have dsorg PS, PO or PO-E and have recfm beginning
+     * with F or V, is fully parsed.
+     *
+     * The following fields in FTPFile is used: FTPFile.Rawlisting: Always set.
+     * FTPFile.Type: DIRECTORY_TYPE or FILE_TYPE or UNKNOWN FTPFile.Name: name
+     * FTPFile.Timestamp: change time or null
+     *
+     *
+     *
+     * Additional information ======================
+     *
+     * The MVS ftp server supports a number of features via the FTP interface.
+     * The features are controlled with the FTP command quote site filetype=<SEQ|JES|DB2>
+     * SEQ is the default and used for normal file transfer JES is used to
+     * interact with the Job Entry Subsystem (JES) similar to a job scheduler
+     * DB2 is used to interact with a DB2 subsystem
+     *
+     * This parser supports SEQ and JES.
