Method Detail

printHardwareList

@Command(type=QUERY,
         level=1,
         description="print my hardware list; for tests")
public String printHardwareList()

getTcpProxy

public CanOpenProxy getTcpProxy()

Specified by:

getTcpProxy in interface BridgeToHardware

startServer

public void startServer()

Specified by:

startServer in interface BridgeToHardware

startThreadReader

public void startThreadReader()

Specified by:

startThreadReader in interface BridgeToHardware

isCWrapperConnected

public boolean isCWrapperConnected()

This method returns true if the C-Wrapper is connected to the tcp proxy. The C-Wrapper has to send the tcpProxy clientName as a keyword before any communication can begin. So if the C-Wrapper doesn't send the good keyword or if it doesn't connect to the tcp proxy, this method returns false.

Specified by:

isCWrapperConnected in interface BridgeToHardware

Returns:

isCANDevicesReady

public boolean isCANDevicesReady()

returns true if the hardware is booted, identified and initialized.

Specified by:

isCANDevicesReady in interface BridgeToHardware

Returns:

isRealHardware

public boolean isRealHardware()

This methods has to be overridden in a simulation context.

Specified by:

isRealHardware in interface BridgeToHardware

Returns:

initModule

public void initModule()

Overrides:

initModule in class org.lsst.ccs.framework.Module

readPDOs

public PDOStorage readPDOs()

Specified by:

readPDOs in interface BridgeToHardware

toString

public String toString()

Overrides:

toString in class Object
