 The type of the difference between two positions.
typedef R Reference
 The type of the reference to the values accessed.

Public Member Functions

Member Typedef Documentation

template<class T, class V, class R = V&, class D = std::ptrdiff_t>
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;

 // Compare for equality with j
 equals(i);

 // 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 wether
 // the same containers are referenced
 DifferenceType distanceTo(j) const;

For an elaborate explanation see the STL Documentation


Member Function Documentation

template<class T, class V, class R = V&, class D = std::ptrdiff_t>
Reference Dune::RandomAccessIteratorFacade< T, V, R, D >::operator[] ( DifferenceType  n  )  const [inline]

Get the element n positions from the current one.

Parameters:
n The distance to the element.
Returns:
The element at that distance.
