Member Function Documentation

bool sick_scan::ColaTransmitter::close ( void )

virtual

Closes the tcp connection to the localization server.

Returns: always true

Definition at line 104 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::connect ( void )

virtual

Connects to the localization server.

Returns: true on success, false on failure (localization server unknown or unreachable)

Definition at line 95 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::dataEndWithETX	(	const std::vector< uint8_t > &	data,
		const std::vector< uint8_t > &	etx
	)

staticprotected

Returns true, if data end with etx, i.e. the trailing (etx.size()) byte in data are identical to etx.

Parameters

[in]	data	data received
[in]	etx	ETX tag (binary or ascii)

Returns: true if data end with etx, false otherwise

Definition at line 237 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::receive	(	std::vector< uint8_t > &	telegram,
		double	timeout,
		ROS::Time &	receive_timestamp
	)

virtual

Receive a cola telegram from the localization server.

Parameters

[out]	telegram	telegram received (Cola-Binary or Cola-Ascii)
[in]	timeout	timeout in seconds
[out]	receive_timestamp	receive timestamp in seconds (ros timestamp immediately after first response byte received)

Returns: true on success, false on failure (connection error or timeout)

Receive a cola telegram from the localization server.

Parameters

[out]	telegram	telegram received (Cola-Binary or Cola-Ascii)
[in]	timeout	timeout in seconds
[out]	receive_timestamp	receive timestamp in seconds (ros timestamp immediately after first response byte received)

Returns: true on success, false on failure

Definition at line 166 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::receive	(	boost::asio::ip::tcp::socket &	socket,
		std::vector< uint8_t > &	telegram,
		double	timeout,
		ROS::Time &	receive_timestamp
	)

static

Receive a cola telegram from a socket.

Parameters

[in]	socket	socket to read from
[out]	telegram	telegram received (Cola-Binary or Cola-Ascii)
[in]	timeout	timeout in seconds
[out]	receive_timestamp	receive timestamp in seconds (ros timestamp immediately after first response byte received)

Returns: true on success, false on failure (connection error or timeout)

Receive a cola telegram from a socket.

Parameters

[in]	socket	socket to read from
[out]	telegram	telegram received (Cola-Binary or Cola-Ascii)
[in]	timeout	timeout in seconds
[out]	receive_timestamp	receive timestamp in seconds (ros timestamp immediately after first response byte received)

Returns: true on success, false on failure

Definition at line 179 of file cola_transmitter.cpp.

void sick_scan::ColaTransmitter::runReceiverThreadCb ( void )

protected

Thread callback, receives response telegrams from localization server and pushes them to m_response_fifo.

Definition at line 311 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::send	(	const std::vector< uint8_t > &	data,
		ROS::Time &	send_timestamp
	)

virtual

Send data to the localization server.

Parameters

[in]	data	data to be send
[out]	send_timestamp	send timestamp in seconds (ros timestamp immediately before tcp send)

Returns: true on success, false on failure

Definition at line 125 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::send	(	boost::asio::ip::tcp::socket &	socket,
		const std::vector< uint8_t > &	data,
		ROS::Time &	send_timestamp
	)

static

Send data to the localization server.

Parameters

[in]	socket	socket to write to
[in]	data	data to be send
[out]	send_timestamp	send timestamp in seconds (ros timestamp immediately before tcp send)

Returns: true on success, false on failure

Definition at line 137 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::startReceiverThread ( void )

virtual

Starts a thread to receive response telegrams from the localization server. The receiver thread pushes responses to a fifo buffer, which can be popped by waitPopResponse().

Returns: always true

Definition at line 254 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::stopReceiverThread ( void )

virtual

Stops the thread to receive response telegrams from the localization server (if a thread has been started by startReceiverThread=.

Returns: always true

Definition at line 266 of file cola_transmitter.cpp.

bool sick_scan::ColaTransmitter::waitPopResponse	(	std::vector< uint8_t > &	telegram,
		double	timeout,
		ROS::Time &	receive_timestamp
	)

virtual

Returns a response telegram from the localization server. This function waits with timout, until the receiver thread received a response telegram from the localization server. Note: The receiver thread must have been started by startReceiverThread(), otherwise waitPopResponse() will fail after timout.

Parameters

[out]	telegram	telegram received (Cola-Binary or Cola-Ascii)
[in]	timeout	timeout in seconds
[out]	receive_timestamp	receive timestamp in seconds (ros timestamp immediately after first response byte received)

Returns: true on success, false on failure (connection error or timeout)
