Class NceSensorManager

java.lang.Object
  jmri.AbstractManager
      jmri.AbstractSensorManager
          jmri.jmrix.nce.NceSensorManager

All Implemented Interfaces:

PropertyChangeListener, EventListener, AbstractMRListener, NceListener, Manager, SensorManager

public class NceSensorManager
extends AbstractSensorManager
implements NceListener

Manage the NCE-specific Sensor implementation.

System names are "NSnnn", where nnn is the sensor number without padding.

This class is responsible for generating polling messages for the NceTrafficController, see nextAiuPoll()
