Member Typedef Documentation

◆ DerivedType

typedef ArrayListIterator< T, N, A > Dune::RandomAccessIteratorFacade< ArrayListIterator< T, N, A > , A::value_type , A::value_type & , 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:493
A::value_type & Reference
The type of the reference to the values accessed.
Definition: iteratorfacades.hh:498
bool equals(const ArrayListIterator< MemberType, N, A > &other) const
Compares two iterators.
Definition: arraylist.hh:571
void increment()
Increment the iterator.
Definition: arraylist.hh:597
void decrement()
decrement the iterator.
Definition: arraylist.hh:609
reference elementAt(size_type i) const
Get the value of the list at an arbitrary position.
Definition: arraylist.hh:621
void advance(difference_type n)
Definition: arraylist.hh:558
reference dereference() const
Access the element at the current position.

◆ operator[]()

Reference Dune::RandomAccessIteratorFacade< ArrayListIterator< T, N, A > , A::value_type , A::value_type & , 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.

◆ position()

Member Data Documentation

◆ chunkSize_

template<class T , int N, class A >
constexpr int Dune::ArrayListIterator< 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.
