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 Details

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()

Get an array of appearance indexes valid for the mast type.

Specified by:

getValidStates in interface SignalHead

Overrides:

getValidStates in class DefaultSignalHead

Returns:

array of appearance state values available on this mast type

getValidStateKeys

public String[] getValidStateKeys()

Get an array of non-localized appearance keys valid for the mast type. For GUI application consider using (capitalized) SignalHead.getValidStateNames()

Specified by:

getValidStateKeys in interface SignalHead

Overrides:

getValidStateKeys in class DefaultSignalHead

Returns:

array of translated appearance names available on this mast type

getValidStateNames

public String[] getValidStateNames()

Get an array of localized appearance descriptions valid for the mast type. For persistance and comparison consider using SignalHead.getValidStateKeys()

Specified by:

getValidStateNames in interface SignalHead

Overrides:

getValidStateNames in class DefaultSignalHead

Returns:

array of translated appearance names

isTurnoutUsed

public boolean isTurnoutUsed(Turnout t)

Description copied from class: AbstractSignalHead

Check if a given turnout is used on this head.

Overrides:

isTurnoutUsed in class TripleTurnoutSignalHead

Parameters:

t - Turnout object to check

Returns:

true if turnout is configured as output or driver of head
