The sole constructor for an NTFTPEntryParser object.

Throws:
IllegalArgumentException Thrown if the regular expression is unparseable. Should not be seen under normal conditions. It it is seen, this is a sign that REGEX is not a valid regular expression.
 
     public NTFTPEntryParser()
     {

This constructor allows the creation of an NTFTPEntryParser object with something other than the default configuration.

Parameters:
config The configuration object used to configure this parser.
Throws:
IllegalArgumentException Thrown if the regular expression is unparseable. Should not be seen under normal conditions. It it is seen, this is a sign that REGEX is not a valid regular expression.
Since:
1.4
 
      public NTFTPEntryParser(FTPClientConfig config)

         configure(config);
         FTPClientConfig config2 = new FTPClientConfig(

Parses a line of an NT FTP server file listing and converts it into a usable format in the form of an FTPFile instance. If the file listing line doesn't describe a file, null is returned, otherwise a FTPFile instance representing the files in the directory is returned.

Parameters:
entry A line of text from the file listing
Returns:
An FTPFile instance corresponding to the supplied entry
 
//    @Override
    public FTPFile parseFTPEntry(String entry)
    {
        FTPFile f = new FTPFile();
        f.setRawListing(entry);
        if (matches(entry))
        {
            String datestr = group(1)+" "+group(2);
            String dirString = group(3);
            String size = group(4);
            String name = group(5);
            try
            {
                f.setTimestamp(super.parseTimestamp(datestr));
            }
            catch (ParseException e)
            {
                // parsing fails, try the other date format
                try
                {
                    f.setTimestamp(.parseTimestamp(datestr));
                }
                catch (ParseException e2)
                {
                    // intentionally do nothing
                }
            }
            if (null == name || name.equals(".") || name.equals(".."))
            {
                return (null);
            }
            f.setName(name);
            if ("<DIR>".equals(dirString))
            {
                f.setType(FTPFile.DIRECTORY_TYPE);
                f.setSize(0);
            }
            else
            {
                f.setType(FTPFile.FILE_TYPE);
                if (null != size)
                {
                  f.setSize(Long.parseLong(size));
                }

        return null;
    }

    
Defines a default configuration to be used when this class is instantiated without a FTPClientConfig FTPClientConfig parameter being specified.

Returns:
the default configuration for this parser.
    @Override
    public FTPClientConfig getDefaultConfiguration() {
        return new FTPClientConfig(
                FTPClientConfig.SYST_NT,
                ,
