Detailed Description

template<class DataPoint, class _WFunctor, typename T = void>
class Ponca::PrimitiveBase< DataPoint, _WFunctor, T >

Primitive base class.

This class stores and provides public access to the fitting state, and must be inherited by classes implementing new primitives.

Note: This class should not be inherited explicitly: this is done by the #Basket class.
