Constructor Detail

LoaderMain

public LoaderMain(BridgeToHardware bridge)

Build a LoaderMainModule with a bridge.

Parameters:

bridge -

Method Detail

init

public void init()

updateStateWithSensors

@Command(type=QUERY,
         level=0,
         description="Update loader state in reading the sensors.")
public void updateStateWithSensors()

Update loader state in reading the sensors.

Specified by:

updateStateWithSensors in class MainModule

Throws:

FcsHardwareException

updateFCSStateToReady

@Command(type=QUERY,
         level=1,
         description="Update FCS state and FCS readyness state and publishes on the status bus.")
public void updateFCSStateToReady()

Check that Loader hardware is ready to be operated and moved. This means that : - all CAN open devices are booted, identified and initialized, - locateHardware has been done on the controllers. This updates the FCS state and FCS readyness state and publishes on the status bus.

Overrides:

updateFCSStateToReady in class MainModule

initializeHardware

public void initializeHardware()

Description copied from class: MainModule

initialize hardware after initialization. to be executed if during boot process some hardware is missing. this method had to be overriden in subclasses.

Specified by:

initializeHardware in class MainModule

connectLoader

@Command(type=ACTION,
         level=0,
         description="Connect the loader hardware.")
public void connectLoader()

Connect the loader hardware.

postStart

public void postStart()

In Standalone mode, we want to connect Loader when the subsystem starts.

printHardwareState

@Command(type=QUERY,
         level=1,
         description="Print the list of hardware with initialization information.")
public String printHardwareState()

Print list of hardware with initialization information.

Returns:

toString

public String toString()

Overrides:

toString in class Object
