newer FTPFileEntryParser interfaces with default functionality.
All the classes in the parser subpackage inherit from this.

Constructor Detail
RegexFTPFileEntryParserImpl
public RegexFTPFileEntryParserImpl(String regex)(Code)
The constructor for a RegexFTPFileEntryParserImpl object.
Parameters: regex - The regular expression with which this object isinitialized. exception: IllegalArgumentException - Thrown if the regular expression is unparseable. Should not be seen innormal conditions. It it is seen, this is a sign that a subclass hasbeen created with a bad regular expression. Since the parser must becreated before use, this means that any bad parser subclasses createdfrom this will bomb very quickly, leading to easy detection.

method.
Parameters: matchnum - match group number to be retrieved the content of the matchnum'th group of the internalmatch or null if this method is called without a match havingbeen made.
Convenience method delegates to the internal MatchResult's matches()
method.
