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.

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

构造器详细资料

UnixFTPEntryParser

public UnixFTPEntryParser()

The default constructor for a UnixFTPEntryParser object.

抛出:

java.lang.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.

UnixFTPEntryParser

public UnixFTPEntryParser(FTPClientConfig config)

This constructor allows the creation of a UnixFTPEntryParser object with something other than the default configuration.

参数:

config - The configuration object used to configure this parser.

抛出:

java.lang.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.

UnixFTPEntryParser

public UnixFTPEntryParser(FTPClientConfig config,
                  boolean trimLeadingSpaces)

This constructor allows the creation of a UnixFTPEntryParser object with something other than the default configuration.

参数:

config - The configuration object used to configure this parser.

trimLeadingSpaces - if true, trim leading spaces from file names

抛出:

java.lang.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.

方法详细资料

preParse

public java.util.List<java.lang.String> preParse(java.util.List<java.lang.String> original)

Preparse the list to discard "total nnn" lines

指定者:

preParse 在接口中 FTPFileEntryParser

覆盖:

preParse 在类中 FTPFileEntryParserImpl

参数:

original - Original list after it has been created from the server stream

返回:

original unmodified.

parseFTPEntry

public FTPFile parseFTPEntry(java.lang.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.

参数:

entry - A line of text from the file listing

返回:

An FTPFile instance corresponding to the supplied entry

getDefaultConfiguration

protected FTPClientConfig getDefaultConfiguration()

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

指定者:

getDefaultConfiguration 在类中 ConfigurableFTPFileEntryParserImpl

返回:

the default configuration for this parser.
