+--de.mud.jta.plugin.Script
- All Implemented Interfaces:
- FilterPlugin
- public class Script
- extends Plugin
- implements FilterPlugin
The script plugin takes a series of match and answer pairs to compare
the incoming data with the matches and if it succeeds writes the answers
back. It then moves on to the next match until all script elements have
matched.
The script property Script.script should contain | separated strings
where each two represent a match and answer pair. A newline will be appended
to each answer!
If the first matching string is empty, the answer string will be sent upon
connect.
The script is very basic but is a very good example how to
write a plugin for The Javatm Telnet Application.
