◆ DerivedType

typedef RealIterator< T, R > Dune::RandomAccessIteratorFacade< RealIterator< T, R > , T , R, std::ptrdiff_t >::DerivedType
inherited

The type of derived iterator.

The iterator has to define following functions have to be present:

// Access the value referred to.
// Access the value at some other location
Reference elementAt(n) const;
// 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;
std::ptrdiff_t 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
bool equals(const RealIterator &it) const

◆ operator[]()

Reference Dune::RandomAccessIteratorFacade< RealIterator< T, R > , T , R, std::ptrdiff_t >::operator[] ( DifferenceType  n) const
inlineinherited

Get the element n positions from the current one.

Parameters
nThe distance to the element.
Returns
The element at that distance.
