Class DoubleTurnoutSignalHead

java.lang.Object
  jmri.AbstractNamedBean
      jmri.AbstractSignalHead
          jmri.DefaultSignalHead
              jmri.DoubleTurnoutSignalHead

All Implemented Interfaces:

Serializable, NamedBean, SignalHead

public class DoubleTurnoutSignalHead
extends DefaultSignalHead

Drive a single signal head via two "Turnout" objects.

After much confusion, the user-level terminology was changed to call these "Double Output"; the class name remains the same to reduce recoding.

The two Turnout objects are provided during construction, and each drives a specific color (RED and GREEN). Normally, "THROWN" is on, and "CLOSED" is off. YELLOW is provided by turning both on ("THROWN")

This class doesn't currently listen to the Turnout's to see if they've been changed via some other mechanism.

Method Detail

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

getRed

public Turnout getRed()

getGreen

public Turnout getGreen()

setRed

public void setRed(Turnout t)

setGreen

public void setGreen(Turnout t)
