Detailed Description

template<class SEQUENCE>
class vigra::SequenceAccessor< SEQUENCE >

Accessor for items that are STL compatible sequences.

It encapsulates access to the sequences' begin() and end() functions.

Usage:

#include <vigra/accessor.hxx>
Namespace: vigra

typedef std::list<std::list<int> > ListOfLists;

ListOfLists ll;
...

typedef vigra::SequenceAccessor<ListOfLists::value_type> ListOfListsAccessor;
ListOfListsAccessor a;
for(ListOfLists::iterator li = ll.begin(); li != ll.end(); ++li)
{
    for(ListOfListsAccessor::iterator i = a.begin(li); i != a.end(li); ++i)
    {
         i = 10;
    }
}
