All Implemented Interfaces:

Serializable, NamedBean, SignalHead

public class MergSD2SignalHead
extends DefaultSignalHead

Implement SignalHead for the MERG Signal Driver 2.

The Signal Driver, runs off of the output of a steady State Accessory decoder. and can be configured to run 2, 3 or 4 Aspect signals. With 2 or 3 aspect signals being able to have a feather included. The class assigns turnout positions for RED, YELLOW, GREEN and Double Yellow aspects. THE SD2 does not support flashing double yellow aspects on turnouts, an alternative method is required to do this, as per the MERG SD2 documentation. nb As there is no Double Yellow asigned within JMRI, we use the Flash Yellow instead.

For more info on the signals, see http://www.merg.info.

Method Detail

setAppearance

public void setAppearance(int newAppearance)

Specified by:

setAppearance in interface SignalHead

Overrides:

setAppearance in class DefaultSignalHead

setLit

public void setLit(boolean newLit)

Specified by:

setLit in interface SignalHead

Overrides:

setLit in class DefaultSignalHead

updateOutput

protected void updateOutput()

Description copied from class: DefaultSignalHead

Type-specific routine to handle output to the layout hardware. Does not notify listeners of changes; that's done elsewhere. Should use the following variables to determine what to send:

• mAppearance
• mLit
• mFlashOn

Specified by:

updateOutput in class DefaultSignalHead

dispose

public void dispose()

Remove references to and from this object, so that it can eventually be garbage-collected.

Specified by:

dispose in interface NamedBean

Overrides:

dispose in class AbstractNamedBean
