function¶

class function_t : public wt::spectrum::spectrum_real_t

(Real-valued) spectrum that is an (arbitrary) function of several nested spectra.

Public Types

using spectra_container_t = std::vector<std::shared_ptr<spectrum_real_t>>

using func_t = unique_function<f_t(const spectra_container_t&, const wavenumber_t) const noexcept>

Public Functions

inline function_t(std::string id, spectra_container_t &&spectra, func_t &&func, std::string func_description)

inline function_t(std::string id, func_t &&func, std::string func_description)

function_t(function_t&&) = default

virtual ~function_t() noexcept = default

inline virtual const distribution1d_t *distribution() const noexcept override: Returns the underlying spectrum distribution.

inline virtual f_t power() const noexcept override: Returns the total spectral power contained in this spectrum.

inline virtual f_t power(const range_t<wavenumber_t> &wavenumbers) const noexcept override: Returns the spectral power over the provided wavenumber range.

inline virtual range_t<wavenumber_t> wavenumber_range() const noexcept override: Returns the range of wavenumbers for which this spectrum is defined. Querying the spectrum with wavenumber<range.min or wavenumber>range.max will always be 0.

inline virtual wavenumber_t mean_wavenumber() const noexcept override: Returns the mean wavenumber for this spectrum.

inline virtual f_t f(const wavenumber_t wavenumber) const noexcept override: Query the spectrum. Returns the spectral power for the given wavenumber ‘wavenumber’.

virtual scene::element::info_t description() const override

Public Static Functions

static std::unique_ptr<spectrum_t> load(std::string id, scene::loader::loader_t *loader, const scene::loader::node_t &node, const wt::wt_context_t &context)
