                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Hello, I can&apos;t find a finalize reference in mapreduce function with java api in anywhere..&lt;br/&gt;
Is there anyway can implement mapreduce funtion with java api like this:&lt;br/&gt;
collection.mapreduce(String map, String reduce, String finalize, String OutPutTarget....)&lt;/p&gt;

&lt;p&gt;Thanks!!!&lt;/p&gt;

                            <comment id="336161" author="samk" created="Wed, 15 May 2013 13:24:32 +0000"  >&lt;p&gt;&lt;a href=&quot;http://api.mongodb.org/java/current/com/mongodb/MapReduceCommand.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://api.mongodb.org/java/current/com/mongodb/MapReduceCommand.html&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Because MapReduce is a Database command that use javascript on the server, finalize functions are the same in the shell as they are in Java or any other language.&lt;/p&gt;

&lt;p&gt;I hope this helps. &lt;/p&gt;</comment>
