< p > This class is the reverse class adaptor for all dbstl iterator classes. < / p >
< p > It inherits from real iterator classes like < a class = "link" href = "db_vector_iterator.html" title = "Chapter 13. Db_vector_iterator" > db_vector_iterator< / a >
, < a class = "link" href = "db_map_iterator.html" title = "Chapter 16. Db_map_iterator" > db_map_iterator< / a >
or < a class = "link" href = "db_set_iterator.html" title = "Chapter 19. Db_set_iterator" > db_set_iterator< / a >
. When you call container::rbegin(), you will get an instance of this class. < / p >
