Class FTPFileEntryParserImpl

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.
StringreadNextEntry(BufferedReader reader)
Reads the next entry using the supplied BufferedReader object up to whatever delemits one entry from the next.

The constructor for a FTPFileEntryParserImpl object.

Method Detail

preParse

public 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. This default implementation removes entries that do not parse as files.

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

Returns: original unmodified.

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 default implementation simply calls BufferedReader.readLine().

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

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

Throws: java.io.IOException thrown on any IO Error reading from the reader.
