Detailed Description

template<class C, class T, class R = T&>
class Dune::DenseIterator< C, T, R >

Generic iterator class for dense vector and matrix implementations.

provides sequential access to DenseVector, FieldVector and FieldMatrix

Member Typedef Documentation

DerivedType

typedef DenseIterator< C, T, T & > Dune::RandomAccessIteratorFacade< DenseIterator< C, T, T & > , T , T & , 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 wether
// the same containers are referenced
DifferenceType distanceTo(j) const;

Get the element n positions from the current one.

Parameters

n	The distance to the element.

Returns

The element at that distance.
