Detailed Description

class Dune::RandomAccessIteratorFacade< T, V, R, D >

Base class for stl conformant forward iterators.

Member Typedef Documentation

DerivedType

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

Member Function Documentation

operator[]()

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.
