Detailed Description

template<class CW, class T, class R>
class Dune::ContainerWrapperIterator< CW, T, R >

Iterator class for sparse vector-like containers.

This class provides an iterator for sparse vector like containers. It contains a ContainerWrapper that must provide the translation from the position in the underlying container to the index in the sparse container.

The ContainerWrapper must be default and copy-constructable. Furthermore it must provide the methods:

bool identical(other) - check if this is identical to other (same container, not only equal) T* pointer(position) - get pointer to data at position in underlying container size_t realIndex(position) - get index in sparse container for position in underlying container

Notice that the iterator stores a ContainerWrapper. This allows one to use proxy classes as underlying container and as returned reference type.

Template Parameters
CWThe container wrapper class
TThe contained type
RThe reference type returned by dereference

◆ DerivedType

typedef ContainerWrapperIterator< CW, T, R > Dune::BidirectionalIteratorFacade< ContainerWrapperIterator< CW, T, R > , T , R, int >::DerivedType

The type of derived iterator.

The iterator has to define following functions have to be present:

// Access the value referred to.
Reference dereference() 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()
R Reference
The type of the reference to the values accessed.
