Class VMSVersioningFTPEntryParser

Implemented Interfaces:
Configurable, FTPFileEntryParser, FTPFileListParser

public class VMSVersioningFTPEntryParser
extends VMSFTPEntryParser

Special implementation VMSFTPEntryParser with versioning turned on. This parser removes all duplicates and only leaves the version with the highest version number for each filename. This is a sample of VMS LIST output "1-JUN.LIS;1 9/9 2-JUN-1998 07:32:04 [GROUP,OWNER] (RWED,RWED,RWED,RE)", "1-JUN.LIS;2 9/9 2-JUN-1998 07:32:04 [GROUP,OWNER] (RWED,RWED,RWED,RE)", "DATA.DIR;1 1/9 2-JUN-1998 07:32:04 [GROUP,OWNER] (RWED,RWED,RWED,RE)",
