|

<p><a class="link" href="db_map.html" title="Chapter 5. Db_map">db_map</a>
|
||
has two iterator class templates -- <a class="link" href="db_map_base_iterator.html" title="Chapter 15. Db_map_base_iterator">db_map_base_iterator</a>
|
||
and <a class="link" href="db_map_iterator.html" title="Chapter 16. Db_map_iterator">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 5. Db_map">db_map</a>
|
||
and <a class="link" href="db_multimap.html" title="Chapter 6. Db_multimap">db_multimap</a>
|
||
. <a class="link" href="db_map_iterator.html" title="Chapter 16. Db_map_iterator">db_map_iterator</a>
|
||
inherits from <a class="link" href="db_map_base_iterator.html" title="Chapter 15. Db_map_base_iterator">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 10. Db_base_iterator">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 15. Db_map_base_iterator">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 16. Db_map_iterator">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>
