typedef T Dune::RandomAccessIteratorFacade< T, V, R, D >::DerivedType |
The type of derived iterator.
The iterator has to define following functions have to be present:
// Access the value referred to.
Reference dereference() const;
// Access the value at some other location
// Compare for equality with j
bool equals(j);
// position the iterator at the next element.
void increment()
// position the iterator at the previous element.
void decrement()
// advance the iterator by a number of positions-
void advance(DifferenceType n);
// calculate the distance to another iterator.
// One should incorporate an assertion whether
// the same containers are referenced
DifferenceType distanceTo(j) const;
D DifferenceType
The type of the difference between two positions.
Definition: iteratorfacades.hh:490
R Reference
The type of the reference to the values accessed.
Definition: iteratorfacades.hh:495
constexpr auto equals(T1 &&t1, T2 &&t2)
Equality comparison.
Definition: hybridutilities.hh:400
constexpr decltype(auto) elementAt(Container &&c, Index &&i)
Get element at given position from container.
Definition: hybridutilities.hh:133
