Detailed Description

template<std::size_t dim, class Index_ = std::size_t>
class Dune::GeneralVertexOrder< dim, Index_ >::iterator

Iterate over the vertex indices of some sub-entity.

This is a random access iterator with constant value_type.

Member Typedef Documentation

DerivedType

typedef iterator Dune::RandomAccessIteratorFacade< iterator , const Index_ , const Index_ & , std::ptrdiff_t >::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;

Constructor & Destructor Documentation

iterator()

template<std::size_t dim, class Index_ = std::size_t>

Dune::GeneralVertexOrder< dim, Index_ >::iterator::iterator ( )

inline

public default constructor

The constructed iterator object will have a singular value. The only valid operations will be assignment of a non-singular value and destruction, all other operations will result in undefined behavior.

Member Function Documentation

operator[]()

constexpr Reference Dune::RandomAccessIteratorFacade< iterator , const Index_ , const Index_ & , std::ptrdiff_t >::operator[] ( DifferenceType  n ) const

inlineconstexprinherited

Get the element n positions from the current one.

Parameters

n	The distance to the element.

Returns

The element at that distance.
