Detailed Description

template<class FUNC>
class sgpp::base::sweep< FUNC >

Standard sweep operation FUNC should be a class with overwritten operator().

For an example see laplace_up_functor in laplace.hpp. It must be default constructable or copyable. STORAGE must provide a grid_iterator supporting left_child, step_right, up, hint and seq.
