Class ListLoader

java.lang.Object
  de.xeinfach.kafenio.util.ListLoader

public final class ListLoader

extends java.lang.Object

This is a static utility class used to load a list of images or links or whatever from the server. Used in Kafenio Applet for Image-from-Server and HyperLink insertion

The Servlet or CGI script should return a list of lines:

• The first one is a prefix (or an empty line meaning there's no prefix)
• The following lines should have a following form: [name/description;;]partial_url

Configuration parameter SERVLETMODE controls how this class reads the lines:

• given the parameter value "java" it is done via an ObjectStream
• and given "cgi" - interating an InputStream.readLine()

Loaded info is parsed into the two lists:

• The list of names or in case there're no names - the list of partial URLs
• The list of full URLs with prefix prepended

The class handles exceptions gracefully, returning empty lists.
