Detailed Description

template<class T, int N, class A>
class Dune::ConstArrayListIterator< T, N, A >

A constant random access iterator for the Dune::ArrayList class.

Member Typedef Documentation

const_reference

template<class T , int N, class A >

using Dune::ConstArrayListIterator< T, N, A >::const_reference = typename A::value_type const&

DerivedType

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

typedef T Dune::RandomAccessIteratorFacade< T, V, R, D >::DerivedType

inherited

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