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.

DerivedType

typedef ConstArrayListIterator< T, N, A > Dune::RandomAccessIteratorFacade< ConstArrayListIterator< T, N, A > , const A::value_type , A::value_type const & , A::difference_type >::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;

Member Function Documentation

operator[]()

Reference Dune::RandomAccessIteratorFacade< ConstArrayListIterator< T, N, A > , const A::value_type , A::value_type const & , A::difference_type >::operator[] ( DifferenceType  n ) const

inlineinherited

Get the element n positions from the current one.

Parameters

n	The distance to the element.

Returns

The element at that distance.

Member Data Documentation

chunkSize_

template<class T , int N, class A >

constexpr int Dune::ConstArrayListIterator< T, N, A >::chunkSize_ = (N > 0) ? N : 1

staticconstexpr

The number of elements in one chunk of the list.

This has to be at least one. The default is 100.
