Method Summary

Modifier and Type	Method	Description
void	messageFromManager(LocoNetMessage l)	implementing classes will typically have a function/listener to get updates from the layout, which will then call public void firePropertyChange(String propertyName, Object oldValue, Object newValue) _once_ if anything has changed state (or set the commanded state directly)
void	requestUpdateFromLayout()	Request an update on status by sending a LocoNet message.
void	setKnownState(int s)	User request to set the state, which means that we need to broadcast the new state over the loconet so that other attached devices.

Method Detail

requestUpdateFromLayout

public void requestUpdateFromLayout()

Request an update on status by sending a LocoNet message. The only known way to do this from LocoNet is to request the status of _all_ devices, which is here considered too heavyweight. See LnSensorManager.updateAll()

setKnownState

public void setKnownState(int s)
                   throws JmriException

User request to set the state, which means that we need to broadcast the new state over the loconet so that other attached devices. The incoming message will in turn, be processed by the SensorManager.

Specified by:

setKnownState in interface Sensor

Overrides:

setKnownState in class AbstractSensor

Parameters:

s - the state to set

Throws:

JmriException - if unable to set the state

messageFromManager

public void messageFromManager(LocoNetMessage l)

implementing classes will typically have a function/listener to get updates from the layout, which will then call public void firePropertyChange(String propertyName, Object oldValue, Object newValue) _once_ if anything has changed state (or set the commanded state directly)

Parameters:

l - LocoNet message from manager.
