class Data : public IData<Data<T>, Base<T>>

Public Functions

inline Data(const std::vector<std::string> &labels, size_t nsamples, double sample_rate, bool resizable)

Data constructor with the label of the columns, the number of samples and the sample rate.

Parameters

  • columns_label – give a label for each column in the data / set also the number of columns in the dataset

  • nsamples – give the number of samples by column

  • sample_rate –

inline Data(size_t ncolumns, size_t nsamples, double sample_rate, bool resizable)

Data constructor with only the number of columns, the number of samples and the sample rate.

The label of column is generated from the column number (“0”, “1”…,)

Parameters

  • ncolumns –

  • nsamples –

  • sample_rate –

inline Data(const Parameters &parameters)

Data constructor based on the parameters object.

Parameters

parameters – - contains already the column labels either automatically generated based on the number of columns or set directly.

inline void ClearData() override

ClearData - clear the timestamps and the data (done in the columndatatype::Data)

inline Parameters parameters() const
inline double sample_rate() const
inline void set_nsamples(size_t nsamples)
inline uint64_t sample_timestamp(size_t sample = 0) const

sample_timestamp - give the timestamp corresponding to a sample number

Parameters

sample –

Returns

one timestamp

inline const std::vector<uint64_t> &sample_timestamps() const

sample_timestamps - give all the timestamps in the packet

Returns

all timestamps

inline std::vector<uint64_t> &sample_timestamps()
inline void set_sample_timestamp(size_t sample, uint64_t t)

set_sample_timestamp - set one timestamp for a given sample number

Parameters

  • sample –

  • t –

inline void set_sample_timestamps(const std::vector<uint64_t> &t)

set_sample_timestamps - set all timestamps for all sample

Parameters

t –

inline void SerializeFlatBuffer(flexbuffers::Builder &flex_builder) override

FlatbufferDescription - This datatype add in the flexbuffer stream the timestamps and the type name.

Note

the columndata is already taking care of adding the data itself.

Parameters

flex_builder –

inline void SerializeBinary(std::ostream &stream, Serialization::Format format = Serialization::Format::FULL) const override

SerializeBinary - This datatype add in the binary stream the timestamps.

Note

the columndata is taking care of adding the data in the stream.

Parameters

  • stream –

  • format –

inline void SerializeYAML(YAML::Node &node, Serialization::Format format = Serialization::Format::FULL) const override

SerializeYAML - This datatype add as a yaml node the timestamps.

Note

the columndata is taking care of adding the data in the upper node.

Parameters

  • node –

  • format –

inline void YAMLDescription(YAML::Node &node, Serialization::Format format = Serialization::Format::FULL) const override

YAMLDescription - this datatype add to the metadata describing the data format the timestamp format.

Parameters

  • node –

  • format –
