public class DccSignalHead
extends AbstractSignalHead

This class implements a SignalHead that maps the various appearances values to aspect values in the Extended Accessory Decoder Control Packet Format and outputs that packet to the DCC System via the generic CommandStation interface

The mapping is as follows:

0 = RED
1 = YELLOW
2 = GREEN
3 = LUNAR
4 = FLASHRED
5 = FLASHYELLOW
6 = FLASHGREEN
7 = FLASHLUNAR
8 = DARK

The FLASH appearances are expected to be implemented in the decoder.

DccSignalHead

public DccSignalHead(java.lang.String sys)

Method Detail

setAppearance

public void setAppearance(int newAppearance)

Description copied from interface: SignalHead

Set the Signal Head Appearance.

Parameters:

newAppearance - integer representing a valid Appearance for this head

setLit

public void setLit(boolean newLit)

Description copied from interface: SignalHead

setHeld

public void setHeld(boolean newHeld)

Set the held parameter.

Note that this does not directly affect the output on the layout; the held parameter is a local variable which affects the aspect only via higher-level logic.

updateOutput

protected void updateOutput()

useAddressOffSet

public void useAddressOffSet(boolean boo)

useAddressOffSet

public boolean useAddressOffSet()

getOutputForAppearance

public int getOutputForAppearance(int appearance)

setOutputForAppearance

public void setOutputForAppearance(int appearance,
                                   int number)

getDefaultNumberForAppearance

public static int getDefaultNumberForAppearance(int i)

setDccSignalHeadPacketSendCount

public void setDccSignalHeadPacketSendCount(int count)

Set Number of times the packet should be sent to the track.

Parameters:

count - - less than 1 is treated as 1

getDccSignalHeadPacketSendCount

public int getDccSignalHeadPacketSendCount()

Get the number of times the packet should be sent to the track.

Returns:

the count

isTurnoutUsed

public boolean isTurnoutUsed(Turnout t)

Description copied from class: AbstractSignalHead

Check if a given turnout is used on this head.

Specified by:

isTurnoutUsed in class AbstractSignalHead

Parameters:

t - Turnout object to check

Returns:

true if turnout is configured as output or driver of head
