Member Typedef Documentation

◆ DerivedType

typedef ConstArrayListIterator< T, N, A > Dune::RandomAccessIteratorFacade< ConstArrayListIterator< T, N, A > , const A::value_type , A::const_reference , 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.
// Access the value at some other location
// 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-
// calculate the distance to another iterator.
// One should incorporate an assertion whether
// the same containers are referenced
A::difference_type DifferenceType
The type of the difference between two positions.
Definition: iteratorfacades.hh:484
A::const_reference Reference
The type of the reference to the values accessed.
Definition: iteratorfacades.hh:489
void increment()
Increment the iterator.
Definition: arraylist.hh:618
const_reference elementAt(size_type i) const

Member Enumeration Documentation

◆ anonymous enum

template<class T , int N, class A >
anonymous enum
Enumerator
chunkSize_ 

The number of elements in one chunk of the list.

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

Member Function Documentation

◆ operator[]()

Reference Dune::RandomAccessIteratorFacade< ConstArrayListIterator< T, N, A > , const A::value_type , A::const_reference , A::difference_type >::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.
