Typedef Documentation

ResolveRef_t

template<class T>

using Dune::ResolveRef_t = std::remove_reference_t<decltype(Dune::resolveRef(std::declval<T&>()))>

Type trait to resolve std::reference_wrapper.

This is an alias for result of resolveRef. Plain types T or const T are forwarded while for T=std::reference_wrapper<S> the wrapped type S is returned.

Function Documentation

applyPartial()

template<class F, class ArgTuple, class I, I... i>

decltype(auto) Dune::applyPartial	(	F &&	f,
		ArgTuple &&	args,
		std::integer_sequence< I, i... >	)

Apply function with arguments from a given tuple.

Parameters

f	A callable object
args	Tuple containing the arguments
indices	Indices to arguments in tuple as std::integer_sequence

This will call the function with arguments generated by unpacking those entries of the tuple that show up given integer_sequence.
