public abstract class FTPFileEntryParserImpl
extends Object
implements FTPFileEntryParser

This abstract class implements both the older FTPFileListParser and newer FTPFileEntryParser interfaces with default functionality. All the classes in the parser subpackage inherit from this.

Constructor Summary

FTPFileEntryParserImpl()
The constructor for a FTPFileEntryParserImpl object.

Method Summary

List<String>	preParse(List<String> original) This method is a hook for those implementors (such as VMSVersioningFTPEntryParser, and possibly others) which need to perform some action upon the FTPFileList after it has been created from the server stream, but before any clients see the list.
String	readNextEntry(BufferedReader reader) Reads the next entry using the supplied BufferedReader object up to whatever delemits one entry from the next.

Specified by:

preParse in interface FTPFileEntryParser

Parameters:

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