sendThrottleTopic - MQTT topic for sending speed

rcvThrottleTopic - MQTT topic for receiving speed

sendDirectionTopic - MQTT topic for sending direction

rcvDirectionTopic - MQTT topic for receiving direction

sendFunctionTopic - MQTT topic for sending function values

rcvFunctionTopic - MQTT topic for receiving function values

address - loco address to set on throttle

Method Detail

setSpeedSetting

public void setSpeedSetting(float speed)

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.

setIsForward

public void setIsForward(boolean forward)

Set the direction

Specified by:

setIsForward in interface Throttle

Overrides:

setIsForward in class AbstractThrottle

Parameters:

forward - true if forward; false otherwise

sendFunctionGroup

public void sendFunctionGroup(int functionNum,
                              boolean momentary)

Send whole (DCC) Function Group for a particular function number.

Overrides:

sendFunctionGroup in class AbstractThrottle

Parameters:

functionNum - Function Number

momentary - False to send normal function status, true to send momentary.

throttleRelease

protected void throttleRelease()

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.

Specified by:

throttleDispose in class AbstractThrottle

setDccAddress

public int setDccAddress(int newaddress)

getDccAddress

public int getDccAddress()

getLocoAddress

public LocoAddress getLocoAddress()

Description copied from interface: Throttle

Locomotive address. The exact format is defined by the specific implementation, as subclasses of LocoAddress will contain different information.

This is an unbound property.

Specified by:

getLocoAddress in interface Throttle

Returns:

The locomotive address

notifyMqttMessage

public void notifyMqttMessage(java.lang.String receivedTopic,
                              java.lang.String message)

Specified by:

notifyMqttMessage in interface MqttEventListener
