Detailed Description

template<class C, class T, class R>
class Dune::ContainerWrapperIterator< C, 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 to use proxy classes as underlying container and as returned reference type.

Template Parameters

CW	The container wrapper class
T	The contained type
R	The reference type returned by dereference
