Detailed Description

template<typename SpaceEvaluator_, typename TrafoEvaluator_, typename SpaceEvalTraits_>
class FEAT::Space::EvaluatorBase< SpaceEvaluator_, TrafoEvaluator_, SpaceEvalTraits_ >

Basic Space Evaluator CRTP base-class template.

This class is a CRTP base-class used by various finite-element space evaluators to outsource common wrapper code which is independent of the actual finite-element in use.

Template Parameters

SpaceEvaluator_	The space evaluator class that derives from this class template.
TrafoEvaluator_	The trafo evaluator class to be used by this space evaluator.
SpaceEvalTraits_	The evaluator traits of the space evaluator.
