Class DccSignalHead

java.lang.Object
  jmri.AbstractNamedBean
      jmri.AbstractSignalHead
          jmri.DccSignalHead

All Implemented Interfaces:

Serializable, NamedBean, SignalHead

public class DccSignalHead
extends AbstractSignalHead

This class implements a SignalHead the maps the various appearances values to aspect values in the Extended Accessory Decoder Control Packet Format and outputs that packet to the DCC System via the generic CommandStation interface

The mapping is as follows:

0 = DARK
1 = RED
2 = YELLOW
3 = GREEN
4 = FLASHRED
5 = FLASHYELLOW
6 = FLASHGREEN

The FLASH appearances are expected to be implemented in the decoder.

Method Detail

setAppearance

public void setAppearance(int newAppearance)

setLit

public void setLit(boolean newLit)

setHeld

public void setHeld(boolean newHeld)

Set the held parameter.

Note that this does not directly effect the output on the layout; the held parameter is a local variable which effects the aspect only via higher-level logic

updateOutput

protected void updateOutput()
