Class UnixFTPEntryParser


public class UnixFTPEntryParser
extends ConfigurableFTPFileEntryParserImpl

Implementation FTPFileEntryParser and FTPFileListParser for standard Unix Systems. This class is based on the logic of Daniel Savarese's DefaultFTPListParser, but adapted to use regular expressions and to fit the new FTPFileEntryParser interface.
See Also:
FTPFileEntryParser (for usage instructions)

Field Summary

static FTPClientConfig
NUMERIC_DATE_CONFIG
Some Linux distributions are now shipping an FTP server which formats file listing dates in an all-numeric format: "yyyy-MM-dd HH:mm.

Constructor Summary

UnixFTPEntryParser()
The default constructor for a UnixFTPEntryParser object.
UnixFTPEntryParser(FTPClientConfig config)
This constructor allows the creation of a UnixFTPEntryParser object with something other than the default configuration.

Method Summary

protected @Override
FTPClientConfig getDefaultConfiguration()
Defines a default configuration to be used when this class is instantiated without a FTPClientConfig parameter being specified.
FTPFile
parseFTPEntry(String entry)
Parses a line of a unix (standard) FTP server file listing and converts it into a usable format in the form of an FTPFile instance.

Field Details

NUMERIC_DATE_CONFIG

public static final FTPClientConfig NUMERIC_DATE_CONFIG
Some Linux distributions are now shipping an FTP server which formats file listing dates in an all-numeric format: "yyyy-MM-dd HH:mm. This is a very welcome development, and hopefully it will soon become the standard. However, since it is so new, for now, and possibly forever, we merely accomodate it, but do not make it the default.

For now end users may specify this format only via UnixFTPEntryParser(FTPClientConfig). Steve Cohen - 2005-04-17

UnixFTPEntryParser

public UnixFTPEntryParser(FTPClientConfig config)
This constructor allows the creation of a UnixFTPEntryParser object with something other than the default configuration.
Parameters:
config - The configuration object used to configure this parser.
Since:
1.4

Method Details

FTPClientConfig getDefaultConfiguration

protected @Override FTPClientConfig getDefaultConfiguration()
Defines a default configuration to be used when this class is instantiated without a FTPClientConfig parameter being specified.

public FTPFile parseFTPEntry(String entry)
Parses a line of a unix (standard) 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
