fpFitterVariant

using fpFitterVariant

Initial value:

 std::variant<
    fpPeriodicCurve,
    fpConvexCurve,
    fpCurve,
    fpClosedCurve,
    fpConstrainedCurve,
    fpParametricCurve,
    fpSurface,
    fpGridSurface,
    fpGridSpline,
    fpParametricSurface,
    fpPolar,
    fpGridPolar,
    fpSphere,
    fpGridSphere>

Variant of bound concrete subtypes of class(fitpack_fitter).

Stack-allocated tagged union — same size as one wrapper plus a tag (all *_c wrappers share the trivial cptr+is_pointer layout). The alternative-set is the C++-bound concrete subtypes enumerated at generation time.

Function Documentation

wrap_fitpack_fitter()

std::optional< fpFitterVariant > wrap_fitpack_fitter ( fitpack_fitter_c handle, const char * class_name )

inline

Resolve a (handle, class_name) pair into the right concrete variant alternative.

Parameters

handle	A base-class C handle (e.g. from a polymorphic component accessor — any caller that has a fitpack_fitter_c plus the dynamic type name).
class_name	The dynamic Fortran type name string returned alongside the handle (e.g. "fitpack_periodic_curve").

Returns

std::nullopt when handle.cptr is null (component unallocated, or class default arm fired in Fortran).

Exceptions

std::runtime_error

if class_name is null but the handle isn't (a generator bug — the polymorphic accessor's select_type fanout missed an arm) or if class_name does not match any registered subtype (binding/YAML drift — regenerate bindings).

Currently constructs a non-owning view of the handle's storage (is_pointer=true on the inner C handle). A future overload may construct an owned variant from a transferred handle.
