Class kraft.monitor.adapter.LinjaAdapter

java.lang.Object
   |
   +----kraft.monitor.adapter.LinjaAdapter

public class LinjaAdapter
extends Object

Deals with receiving messages from a Linda server on behalf of the Monitor. On startup, connects to a Linda server, and "out"s predicates to inform the Linda server(s) being monitored to make duplicates. for local site: monitor(_) for remote site: remote_monitor(on, _, _) Converts the raw strings received from messages (representing Prolog terms) into Kraft_msg objects, and registers KraftAgents when needed to represent the sender/receiver of messages. It passes these to any MonitorServer, using the standard interface methods. Currently, the MonitorGUI is the one receiving these calls.
