register number currently

setFunction

public void setFunction(int functionNum,
 boolean newState)

Set Loco Function and send to Layout.

Specified by:

setFunction in interface Throttle

Overrides:

setFunction in class AbstractThrottle

Parameters:

functionNum - Function Number, 0-28

newState - New Function State. True on, false off.

sendFunctionGroup1

protected void sendFunctionGroup1()

Overrides:

sendFunctionGroup1 in class AbstractThrottle

sendFunctionGroup2

protected void sendFunctionGroup2()

Send the DCC++ message to set the state of functions F5, F6, F7, F8

Overrides:

sendFunctionGroup2 in class AbstractThrottle

setSpeedSetting

public void setSpeedSetting(float speed)

Description copied from class: AbstractThrottle

setSpeedSetting - Implementing functions should override this function, but should either make a call to super.setSpeedSetting() to notify the listeners at the end of their work, or should notify the listeners themselves.

Specified by:

setSpeedSetting in interface Throttle

Overrides:

setSpeedSetting in class AbstractThrottle

Parameters:

speed - the speed as a 0.0 -> 1.0. fraction of maximum possible speed or -1 for emergency stop.

sendEmergencyStop

protected void sendEmergencyStop()

setIsForward

public void setIsForward(boolean forward)

Description copied from class: AbstractThrottle

Implementing functions should override this function, but should either make a call to super.setIsForward() to notify the listeners, or should notify the listeners themselves.

Overrides:

setIsForward in class AbstractThrottle

Parameters:

forward - true if forward; false otherwise

setSpeedStepMode

public void setSpeedStepMode(SpeedStepMode Mode)

Specified by:

setSpeedStepMode in interface DccThrottle

Overrides:

setSpeedStepMode in class AbstractThrottle

Parameters:

Mode - the current speed step mode

throttleDispose

protected void throttleDispose()

Dispose when finished with this object. After this, further usage of this Throttle object will result in a JmriException. This is quite problematic, because a using object doesn't know when it's the last user.
