constexpr FieldVector() noexcept
Default constructor, making value-initialized vector with all components set to zero.
Definition: fvector.hh:108
Implements a vector constructed from a given type representing a field and a compile-time given size.
Support for calculating hash values of objects.
#define DUNE_DEFINE_HASH(template_args, type)
Defines the required struct specialization to make type hashable via Dune::hash.
Definition: hash.hh:100
#define DUNE_HASH_TYPE(...)
Wrapper macro for the type to be hashed in DUNE_DEFINE_HASH.
Definition: hash.hh:117
#define DUNE_HASH_TEMPLATE_ARGS(...)
Wrapper macro for the template arguments in DUNE_DEFINE_HASH.
Definition: hash.hh:109
Dune namespace.
Definition: alignedallocator.hh:13
constexpr auto back(std::integer_sequence< T, II... > seq)
Return the last entry of the sequence.
