jmri.jmrit.z21server.TurnoutNumberMapHandler

All Implemented Interfaces:

PropertyChangeListener, EventListener

public class TurnoutNumberMapHandler
extends Object
implements PropertyChangeListener

Handle the mapping from a Z21 turnout number to a JMRI Named Bean. This is not restricted to just JMRI turnouts, the mapping works for: - Turnouts - Lights (thrown = ON, closed = OFF - Routes (thrown sets the route, closed does nothing) - Signal Masts and Signal Heads (closed = HELD, thrown = not HELD, the aspect/appearance itself can not be modified) - Sensors (thrown = ACTIVE, closed = INACTIVE). Used to triggers all actions bound to the sensor If a component should be used by a Z21 turnout number, the number will be stored in a property of the bean.
