Direct Known Subclasses:

QuadOutputSignalHead

public class TripleTurnoutSignalHead
extends DoubleTurnoutSignalHead

Drive a single signal head via three "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 three Turnout objects are provided during construction, and each drives a specific color (RED, YELLOW and GREEN). 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 DoubleTurnoutSignalHead

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 DoubleTurnoutSignalHead

getYellow

public NamedBeanHandle<Turnout> getYellow()

setYellow

public void setYellow(NamedBeanHandle<Turnout> t)

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 DoubleTurnoutSignalHead

Parameters:

t - Turnout object to check

Returns:

true if turnout is configured as output or driver of head

readOutput

void readOutput()

Disables the feedback mechanism of the DoubleTurnoutSignalHead.

Overrides:

readOutput in class DoubleTurnoutSignalHead
