Detailed Description
template<class ScalarIn, class ScalarOut, class ActiveOut, class FinalEvaluatorType>
class CppAD::cg::EvaluatorBase< ScalarIn, ScalarOut, ActiveOut, FinalEvaluatorType >
A base class for evaluators. Evaluators allow to reprocess operations defined in an operation graph for a different set of independent variables and (possibly) data types.
Operation implementations (sin(), cos(), ...) should be implemented in a subclass of type FinalEvaluatorType. This allows static polymorphism through curiously recurring template pattern (CRTP). Therefore the default behaviour can be overridden without the use of virtual methods.
This class should not be instantiated directly.
- Todo:
- implement nonrecursive algorithm (so that there will never be any stack limit issues)
