Constructor & Destructor Documentation

virtual CanItf::~CanItf ( )

inlinevirtual

The destructor does not necessarily have to be overwritten. But it makes sense to close any resources like handles.

Definition at line 60 of file CanItf.h.

Member Function Documentation

CanItfType CanItf::getCanItfType ( )

inline

Get the CAN interface type. This is necessary to implement a proper CAN bus simulation.

Returns

The CAN interface type.

Definition at line 121 of file CanItf.h.

virtual void CanItf::init ( )

pure virtual

Initializes the CAN bus.

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

virtual bool CanItf::init_ret ( )

pure virtual

Initializes the CAN bus and returns success.

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

virtual bool CanItf::isObjectMode ( )

pure virtual

Check if the current CAN interface was opened on OBJECT mode.

Returns

true if opened in OBJECT mode, false if not.

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

virtual bool CanItf::receiveMsg ( CanMsg *  pCMsg )

pure virtual

Reads a CAN message.

Returns

true if a message is available

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

virtual bool CanItf::receiveMsgRetry ( CanMsg *  pCMsg, int  iNrOfRetry  )

pure virtual

Reads a CAN message. The function blocks between the attempts.

Parameters

pCMsg	CAN message
iNrOfRetry	number of retries

Returns

true if a message is available

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

virtual bool CanItf::receiveMsgTimeout ( CanMsg *  pCMsg, int  nMicroSecTimeout  )

pure virtual

Reads a CAN message with timeout.

Parameters

pCMsg	CAN message
nMicroSecTimeout	timeout in us

Returns

true if a message is available

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.

void CanItf::setCanItfType ( CanItfType  iType )

inline

Set the CAN interface type. This is necessary to implement a proper CAN bus simulation.

Parameters

iType

The CAN interface type.

Definition at line 114 of file CanItf.h.

virtual bool CanItf::transmitMsg ( CanMsg  CMsg, bool  bBlocking = true  )

pure virtual

Sends a CAN message.

Parameters

pCMsg	CAN message
bBlocking	specifies whether send should be blocking or non-blocking

Implemented in CanESD, SocketCan, CANPeakSysUSB, and CanPeakSys.
