has two iterator class templates -- < a class = "link" href = "db_map_base_iterator.html" title = "Chapter > db_map_base_iterator< / a >
and < a class = "link" href = "db_map_iterator.html" title = "Chapter > db_map_iterator< / a >
. < / p >
< p > They are the const iterator class and iterator class for < a class = "link" href = "db_map.html" title = "Chapter > db_map< / a >
and < a class = "link" href = "db_multimap.html" title = "Chapter > db_multimap< / a >
. < a class = "link" href = "db_map_iterator.html" title = "Chapter > db_map_iterator< / a >
inherits from < a class = "link" href = "db_map_base_iterator.html" title = "Chapter > db_map_base_iterator< / a >
.< / p >
< p > The two classes have identical behaviors to std::map::const_iterator and std::map::iterator respectively. Note that the common public member function behaviors are described in the < a class = "link" href = "db_base_iterator.html" title = "Chapter > db_base_iterator< / a >
section.< / p >
< p > The differences between the two classes are that the < a class = "link" href = "db_map_base_iterator.html" title = "Chapter > db_map_base_iterator< / a >
can only be used to read its referenced value, while < a class = "link" href = "db_map_iterator.html" title = "Chapter > db_map_iterator< / a >
allows both read and write access. If your access pattern is readonly, it is strongly recommended that you use the const iterator because it is faster and more efficient. < / p >
