Field Documentation

template<typename float_type>

const bool c2_transformation< float_type >::fHasStaticTransforms

flag to indicate if the static function pointers can be used for efficiency

Definition at line 1173 of file c2_function.hh.

template<typename float_type>

const bool c2_transformation< float_type >::fTransformed

flag to indicate if this transform is not the identity

Definition at line 1171 of file c2_function.hh.

template<typename float_type>

float_type(* const c2_transformation< float_type >::pIn)(float_type)

non-virtual pointer to input X transform

Note

the pointers to functions allow highly optimized access when static functions are available. They are only used inside value_with_derivatives(), which is assumed to be the most critical routine.
