[dune-fem] LocalEvaluation

[Sahai, Amal]

I had a question regarding the template parameter LocalEvaluation that features in many of the functions in dune-fem-dg such as the following from discretemodelcommon.hh:

    template <class LocalEvaluation>
    double boundaryFlux(const LocalEvaluation& left,
                        RangeType& gLeft,
                        JacobianRangeType& gDiffLeft ) const   /*@LST0E@*/


    template <class LocalEvaluation>
    double numericalFlux(const LocalEvaluation& left,
                         const LocalEvaluation& right,
                         RangeType& gLeft,
                         RangeType& gRight,
                         JacobianRangeType& gDiffLeft,
                         JacobianRangeType& gDiffRight ) const

What kind of structure/class is LocaEvaluation and where is it defined?
