Public Functions

StreamStats() = default

Default constructor, sets everthing to 0.

StreamStats(uint32_t s_id, ts_t receive_ts, ts_t sensor_ts, uint32_t msg_size)

Construct a StreamStats with the specified values.

Parameters:

  • s_id[in] – Specify the stream_id to use.

  • receive_ts[in] – Set the start and end timestamps to the specified value and add it to the receive timestamps.

  • sensor_ts[in] – Add to the sensor timestamps.

  • msg_size[in] – Set the average message size to the specified value.

void update(ts_t receive_ts, ts_t sensor_ts, uint32_t msg_size)

Update values within the StreamStats.

Parameters:

  • receive_ts[in] – Add another receive timestamp and calculate the start and end values.

  • sensor_ts[in] – Add another sensor timestamp

  • msg_size[in] – Add another message size and calculate the average.
