Classes
struct	Dune::Empty
	Just an empty class. More...
struct	Dune::IsInteroperable< T1, T2 >
	Checks whether two types are interoperable. More...
struct	Dune::EnableIfInterOperable< T1, T2, Type >
	Enable typedef if two types are interoperable. More...
struct	Dune::AlwaysFalse< T >
	template which always yields a false value More...
struct	Dune::AlwaysTrue< T >
	template which always yields a true value More...
struct	Dune::IsCallable< F(Args...), R >
	Check if a type is callable with ()-operator and given arguments. More...
struct	Dune::IsNumber< T >
	Whether this type acts as a scalar in the context of (hierarchically blocked) containers. More...
struct	Dune::HasNaN< T >
	Whether this type has a value of NaN. More...
struct	Dune::IsIndexable< T, I >
	Type trait to determine whether an instance of T has an operator[](I), i.e. whether it can be indexed with an index of type I. More...
struct	Dune::IsIterable< T, typename >
	typetrait to check that a class has begin() and end() members More...
struct	Dune::IsTuple< T >
	Check if T is a std::tuple<...> More...
struct	Dune::IsTupleOrDerived< T >
	Check if T derived from a std::tuple<...> More...
struct	Dune::IsIntegralConstant< T >
	Check if T is an std::integral_constant<I, i> More...
struct	Dune::IsCompileTimeConstant< T >
	Check if T is an integral constant or any type derived from std::integral_constant. More...
struct	Dune::AutonomousValueType< T >
	Type free of internal references that T can be converted to. More...
struct	Dune::AutonomousValueType< T & >
	Specialization to remove lvalue references. More...
struct	Dune::AutonomousValueType< T && >
	Specialization to remove rvalue references. More...
struct	Dune::AutonomousValueType< const T >
	Specialization to remove const qualifiers. More...
struct	Dune::AutonomousValueType< volatile T >
	Specialization to remove volatile qualifiers. More...
struct	Dune::AutonomousValueType< std::vector< bool >::reference >
	Specialization for the proxies of vector<bool> More...
struct	Dune::AutonomousValueType< volatile const T >
	Specialization to remove both const and volatile qualifiers. More...

Namespaces
namespace	Dune
	Dune namespace.

Typedefs
template<class... Types>
using	Dune::void_t = typename Impl::voider< Types... >::type
	Is void for all valid input types. The workhorse for C++11 SFINAE-techniques. More...
template<class Type >
using	Dune::field_t = typename FieldTraits< Type >::field_type
	Convenient access to FieldTraits<Type>::field_type.
template<class Type >
using	Dune::real_t = typename FieldTraits< Type >::real_type
	Convenient access to FieldTraits<Type>::real_type.
template<class T >
using	Dune::AutonomousValue = typename AutonomousValueType< T >::type
	Type free of internal references that T can be converted to. More...

Functions
template<class T , T... t, std::size_t index>
constexpr auto	Dune::integerSequenceEntry (std::integer_sequence< T, t... >, std::integral_constant< std::size_t, index > i)
	Get entry of std::integer_sequence. More...
template<class T >
constexpr AutonomousValue< T >	Dune::autoCopy (T &&v)
	Autonomous copy of an expression's value for use in auto type deduction. More...
