All Implemented Interfaces:

Serializable, NamedBean, SignalHead

public class QuadOutputSignalHead
extends TripleTurnoutSignalHead

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

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

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

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

Overrides:

updateOutput in class TripleTurnoutSignalHead

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 TripleTurnoutSignalHead

getLunar

public NamedBeanHandle<Turnout> getLunar()

setLunar

public void setLunar(NamedBeanHandle<Turnout> t)

getValidStates

public int[] getValidStates()

Specified by:

getValidStates in interface SignalHead

Overrides:

getValidStates in class DefaultSignalHead

getValidStateNames

public String[] getValidStateNames()

Specified by:

getValidStateNames in interface SignalHead

Overrides:

getValidStateNames in class DefaultSignalHead
