Constructor Details

VMSFTPEntryParser

public VMSFTPEntryParser()

Constructor for a VMSFTPEntryParser object.

- Thrown if the regular expression is unparseable.

Method Details

isVersioning

protected boolean isVersioning()

parseFTPEntry

public FTPFile parseFTPEntry(String entry)

Parses a line of a VMS 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.

entry - A line of text from the file listing

An FTPFile instance corresponding to the supplied entry

parseFileList

public FTPFile[] parseFileList(InputStream listStream)

Parses an FTP server file listing and converts it into a usable format in the form of an array of FTPFile instances. If the file list contains no files, null should be returned, otherwise an array of FTPFile instances representing the files in the directory is returned.

listStream - The InputStream from which the file list should be read.

The list of file information contained in the given path. null if the list could not be obtained or if there are no files in the directory.

- If an I/O error occurs reading the listStream.

readNextEntry

public String readNextEntry(BufferedReader reader)

Reads the next entry using the supplied BufferedReader object up to whatever delemits one entry from the next. This parser cannot use the default implementation of simply calling BufferedReader.readLine(), because one entry may span multiple lines.

reader - The BufferedReader object from which entries are to be read.

A string representing the next ftp entry or null if none found.

- thrown on any IO Error reading from the reader.
