Detailed Description

template<Concepts::OrderedIndexRange R>
struct Dune::Experimental::OrderedIndexRangeTraits< R >

Traits for sets of indices.

Provides uniform access to the properties of index sets, such as the range of indices covered and the offset of a given index. Specializations for specific index set types can be provided to optimize these operations.

Member Typedef Documentation

index_range_type

template<Concepts::OrderedIndexRange R>

using Dune::Experimental::OrderedIndexRangeTraits< R >::index_range_type = R

The type of the index set.

index_type

template<Concepts::OrderedIndexRange R>

using Dune::Experimental::OrderedIndexRangeTraits< R >::index_type = std::ranges::range_value_t<index_range_type>

The type of indices in the index set.

size_type

template<Concepts::OrderedIndexRange R>

using Dune::Experimental::OrderedIndexRangeTraits< R >::size_type = std::ranges::range_size_t<index_range_type>

The type used to count elements in the index set.

Member Function Documentation

offset()

template<Concepts::OrderedIndexRange R>

static constexpr size_type Dune::Experimental::OrderedIndexRangeTraits< R >::offset ( const R &  index_set, const index_type &  value  )

inlinestaticconstexpr

Offset of value in the index set.

Distance to the to the first element in the index_set which does not compare less than value.

range()

template<Concepts::OrderedIndexRange R>

static constexpr IntegralRange< index_type > Dune::Experimental::OrderedIndexRangeTraits< R >::range ( const R &  index_set )

inlinestaticconstexpr

Logical index range covered by index_set.

Return the smallest half-open integral range containing all indices in index_set.
