LocalAnalyticalFunctionBinder binds a C++ local analytical function (and also its Jacobian and Hessian) to an object which provides all the methods and types needed by the LocalFunctionAdapter. It stores a copy as a std::function. More...

LocalAnalyticalFunctionBinder binds a C++ local analytical function (and also its Jacobian and Hessian) to an object which provides all the methods and types needed by the LocalFunctionAdapter. It stores a copy as a std::function.
Therefore, in order to transform the function
RangeType f(const DomainType& x,double t,const EntityType& entity) { // do stuff }
into a grid function, it is sufficient to pass it to the LocalAnalyticalFucntionBinder
typedef LocalAnalyticalFunctionBinder<DiscreteFunctionSpaceType> LocalAnalyticalFunctionType; LocalAnalyticalFunctionType localAnalyticalFunction(f);
and create the LocalFunctionAdapter
typedef LocalFunctionAdapter<LocalAnalyticalFunctionType> AdaptedFunctionType; AdaptedFunctionType fAdapted("adapted function",localAnalyticalFunction,gridPart);
