Detailed Description

Function Documentation

back()

template<typename... T, typename std::enable_if<(sizeof...(T) > 0), bool >::type = true>

constexpr auto Dune::TypeTree::back ( const HybridTreePath< T... > &  tp ) -> decltype(treePathEntry<sizeof...(T)-1>(tp))

constexpr

Returns a copy of the last element of the HybridTreePath.

As HybridTreePath instances should not be mutated after their creation, this function returns a copy of the value. As values are either std::integral_constant or std::size_t, that's just as cheap as returning a reference.

front()

template<typename... T>

constexpr auto Dune::TypeTree::front ( const HybridTreePath< T... > &  tp ) -> decltype(treePathEntry<0>(tp))

constexpr

Returns a copy of the first element of the HybridTreePath.

As HybridTreePath instances should not be mutated after their creation, this function returns a copy of the value. As values are either std::integral_constant or std::size_t, that's just as cheap as returning a reference.

hybridTreePath()

template<typename... T>

constexpr HybridTreePath< T... > Dune::TypeTree::hybridTreePath ( const T &...  t )

constexpr

Constructs a new HybridTreePath from the given indices.

This function returns a new HybridTreePath with the given index values. It exists mainly to avoid having to manually specify the exact type of the new object.

push_back() [1/2]

template<std::size_t i, typename... T>

constexpr HybridTreePath< T..., index_constant< i > > Dune::TypeTree::push_back ( const HybridTreePath< T... > &  tp, index_constant< i >  i_ = {}  )

constexpr

Appends a compile time index to a HybridTreePath.

This function returns a new HybridTreePath with the compile time index i appended.

The value for the new entry can be passed either as a template parameter or as an index_constant:

auto tp = hybridTreePath(1,2,3,4);
using namespace Dune::TypeTree::Indices;
// the following two lines are equivalent
auto tp_a = push_back<1>(tp);
auto tp_b = push_back(tp,_1);

push_back() [2/2]

template<typename... T>

constexpr HybridTreePath< T..., std::size_t > Dune::TypeTree::push_back ( const HybridTreePath< T... > &  tp, std::size_t  i  )

constexpr

Appends a run time index to a HybridTreePath.

This function returns a new HybridTreePath with the run time index i appended.

constexpr HybridTreePath< index_constant< i >, T... > Dune::TypeTree::push_front ( const HybridTreePath< T... > &  tp, index_constant< i >  _i = {}  )

constexpr

Prepends a compile time index to a HybridTreePath.

This function returns a new HybridTreePath with the compile time index i prepended.

The value for the new entry can be passed either as a template parameter or as an index_constant:

auto tp = hybridTreePath(1,2,3,4);
using namespace Dune::TypeTree::Indices;
// the following two lines are equivalent
auto tp_a = push_front<1>(tp);
auto tp_b = push_front(tp,_1);

push_front() [2/2]

template<typename... T>

constexpr HybridTreePath< std::size_t, T... > Dune::TypeTree::push_front ( const HybridTreePath< T... > &  tp, std::size_t  element  )

constexpr

Prepends a run time index to a HybridTreePath.

This function returns a new HybridTreePath with the run time index i prepended.

treePath()

template<typename... T>

constexpr HybridTreePath< T... > Dune::TypeTree::treePath ( const T &...  t )

constexpr

Constructs a new HybridTreePath from the given indices.

This function returns a new HybridTreePath with the given index values. It exists mainly to avoid having to manually specify the exact type of the new object.

treePathEntry()

template<std::size_t i, typename... T>

constexpr auto Dune::TypeTree::treePathEntry ( const HybridTreePath< T... > &  tp, index_constant< i >  = {}  ) -> typename std::decay<decltype(std::get<i>(tp._data))>::type

constexpr

Returns a copy of the i-th element of the HybridTreePath.

As HybridTreePath instances should not be mutated after their creation, this function returns a copy of the value. As values are either std::integral_constant or std::size_t, that's just as cheap as returning a reference.

The index for the entry can be passed either as a template parameter or as an index_constant:

auto tp = hybridTreePath(1,2,3,4);
using namespace Dune::TypeTree::Indices;
// the following two lines are equivalent
std::cout << treePathEntry<2>(tp) << std::endl;
std::cout << treePathEntry(tp,_2) << std::endl;

treePathIndex()

template<std::size_t i, typename... T>

constexpr std::size_t Dune::TypeTree::treePathIndex ( const HybridTreePath< T... > &  tp, index_constant< i >  = {}  )

constexpr

Returns the index value of the i-th element of the HybridTreePath.

This function always returns the actual index value, irrespective of whether the entry is a compile time index or a run time index.

The index for the entry can be passed either as a template parameter or as an index_constant:

auto tp = hybridTreePath(1,2,3,4);
using namespace Dune::TypeTree::Indices;
// the following two lines are equivalent
std::cout << treePathIndex<2>(tp) << std::endl;
std::cout << treePathIndex(tp,_2) << std::endl;
