Public Functions

inline virtual void decode(const uint8_t *buf, size_t bufSize, EventProcT *processor) override

decode buffer without using message type. Use this method if the message is not available, e.g. when calling from python.

inline virtual size_t decodeUntil(const uint8_t *buf, size_t bufSize, EventProcT *processor, uint64_t timeLimit, uint64_t *nextTime) override

decode buffer until reaching time limit, without using message type. Use this method if the message is not available, e.g. when calling from python.

inline void doDecode(const uint8_t *buf, size_t bufSize, EventProcT *processor, uint64_t timeLimit, size_t *numConsumed, uint64_t *nextTime)
inline virtual bool summarize(const uint8_t *buf, size_t bufSize, uint64_t *firstTS, uint64_t *lastTS, size_t *numEventsOnOff) override

See summarize()

inline virtual void setTimeBase(uint64_t) override

Sets time base, i.e the reference time to which the event times refer to. For some codecs (like evt3) this has no effect.

Parameters:

timeBase – typically time in nanoseconds since epoch.

inline virtual bool findFirstSensorTime(const uint8_t *buf, size_t size, uint64_t *firstTS) override

Finds first sensor time in event packet. This can be much faster than decoding the entire packet.

Parameters:

  • buf – buffer with event data

  • size – size of buffer with event data (bytes)

  • firstTS – first time stamp (only valid if “true” is returned!)

Returns:

true if sensor time has been found

inline virtual bool findFirstSensorTime(const MsgT &msg, uint64_t *firstTS) override

Finds first sensor time in event packet. This can be much faster than decoding the entire packet.

Parameters:

  • msg – event packet message

  • firstTS – first time stamp (only valid if “true” is returned!)

Returns:

true if sensor time has been found

inline virtual void setTimeMultiplier(uint32_t mult) override

Sets the time multiplier.

Parameters:

mult – Time multiplier. If the sensor time is natively in usec and mult is set to 1000, then the decoded time will be in nanoseconds.

inline virtual void setGeometry(uint16_t width, uint16_t height) override

Sets sensor geometry. Must be called before first call to “decode”. Necessary for sanity checks.

Parameters:

  • width – sensor width in pixels

  • height – sensor height in pixels

inline virtual uint16_t getWidth() const override

Gets sensor width.

Returns:

width of sensor

inline virtual uint16_t getHeight() const override

Gets sensor height.

Returns:

height of sensor
