Methods

virtual size_t datasetUI_size() const = 0

Number of different time steps available to call getObservations()

virtual size_t datasetUI_lastQueriedTimestep() const = 0

Returns the latest requested observation, range [0, datasetSize()]

virtual void datasetUI_teleport(size_t timestep) = 0

Forces continue replaying in this moment in time

virtual std::optional<double> datasetUI_time() const

Current dataset playback time, in seconds elapsed since the beginning of the dataset. Returns std::nullopt if the source cannot tell (default).

virtual std::optional<double> datasetUI_total_time() const

Total dataset duration, in seconds. Returns std::nullopt if unknown (default), e.g. for live sources or datasets read on the fly.
