class Singler : public ouster::sdk::core::FrameSetSourceWrapper

FrameSetSource that iterates over a single stream in a FrameSetSource.

Public Functions

Singler(const FrameSetSource &source, size_t idx)

Single the provided source, getting the sensor with the provided index.

Parameters:

  • source[in] source to single

  • idx[in] index of sensor to single out

Singler(FrameSetSource &&source, size_t idx)

Single the provided source, getting the sensor with the provided index.

Parameters:

  • source[in] source to single

  • idx[in] index of sensor to single out

Singler(std::unique_ptr<FrameSetSource> source, size_t idx)

Single the provided source, getting the sensor with the provided index.

Parameters:

  • source[in] source to single

  • idx[in] index of sensor to single out

Singler(Singler &&copy) = default

Move constructor for Singler.

Parameters:

copy[in] The Singler instance to move from.

virtual FrameSetIterator begin() const override

Provides each frame from all sensors in time order.

Returns:

start iterator for all sensors

virtual FrameSetIterator begin(int idx) const override

Provides frames from a single sensor in time order If idx < 0 provides frames from all sensors.

Parameters:

  • sensor_index[in] sensor index

  • sensor_index[in] sensor index

Throws:

std::runtime_error – if sensor_idx >= number of sensors

Returns:

start iterator for the sensor with the given index

virtual FrameSetIterator end() const override

Return the end iterator.

Returns:

end iterator

virtual const std::vector<size_t> &frames_num() const override

Get the frame count for each sensor in the file.

Throws:

std::runtime_error – if unindexed

Returns:

frame count for each sensor in the file

virtual size_t size_hint() const override

The approximate length of the source if unindexed, or the real size if indexed.

Live sources or sources with undefined length will return 0.

Returns:

approximate length of source

virtual bool is_collated() const override

Check if the source provides collated frames.

Returns:

true if collations are provided.

virtual std::unique_ptr<FrameSetSource> move() override

move into a newly allocated item

Returns:

a unique pointer to a newly allocated FrameSetSource instance containing the moved-from state.

virtual const std::vector<std::shared_ptr<SensorInfo>> &sensor_info() const override

Get the sensor info for each sensor in this dataset.

Returns:

sensor info for each sensor

virtual const std::vector<std::pair<uint64_t, uint64_t>> &full_index() const override

timestamp based index of all frames in the file, each pair is timestamp followed by sensor index

Throws:

std::runtime_error – if unindexed

Returns:

index

virtual const std::vector<std::vector<std::pair<uint64_t, uint64_t>>> &individual_index() const override

timestamp based index of all frames in the file for each sensor, each pair is timestamp followed by global frame index

Throws:

std::runtime_error – if unindexed

Returns:

index
