jmri.jmrix.jmriclient
Class JMRIClientTrafficController

java.lang.Object
  jmri.jmrix.AbstractMRTrafficController
      jmri.jmrix.jmriclient.JMRIClientTrafficController

All Implemented Interfaces:

JMRIClientInterface

public class JMRIClientTrafficController
extends AbstractMRTrafficController
implements JMRIClientInterface

Converts Stream-based I/O to/from JMRIClient messages. The "JMRIClientInterface" side sends/receives message objects.

The connection to a JMRIClientPortController is via a pair of *Streams, which then carry sequences of characters for transmission. Note that this processing is handled in an independent thread.

This handles the state transistions, based on the necessary state in each message.
