Fields

uint16_t m_pgn {0}

The Parameter Group Number within this frame.

uint8_t m_src_address {0}

The address of the source node within this frame.

uint8_t m_priority {0}

The priority.

uint8_t m_pdu_format {0}

PDU Format.

uint8_t m_pdu_spec {0}

PDU Specific.

uint8_t m_data_length {0}

Data length.

std::vector<uint8_t> m_data

The data within this frame (0-8 bytes)

std::vector<char> m_raw_frame

The ASCII frame.

Methods

virtual void getSensorPose(mrpt::poses::CPose3D&) const

Not used.

virtual void setSensorPose(const mrpt::poses::CPose3D& newSensorPose)

A general method to change the sensor pose on the robot.

Note that most sensors will use the full (6D) CPose3D, but see the derived classes for more details or special cases.

getSensorPose

virtual void getDescriptionAsText(std::ostream& o) const

Build a detailed, multi-line textual description of the observation contents and dump it to the output stream.

If overried by derived classes, call base CObservation::getDescriptionAsText() first to show common information.

This is the text that appears in RawLogViewer when selecting an object in the dataset
