                    <description>&lt;p&gt;Unused value&lt;/p&gt;

&lt;p&gt; An assigned value that is never used may represent unnecessary computation, an incorrect algorithm, or possibly the need for cleanup or refactoring. A value assigned to a variable is never used.&lt;br/&gt;

                            <comment id="4013207" author="kyle.suarez" created="Fri, 20 Aug 2021 15:20:48 +0000"  >&lt;p&gt;This is for both the &lt;tt&gt;Full&lt;/tt&gt; and &lt;tt&gt;Partition&lt;/tt&gt; parameters in the visitors. (There&apos;s a separate Coverity ticket for each, but combined them both here.) If the parameters are meant to be ignored, I&apos;d prefer to omit the parameter name to suppress these warnings.&lt;/p&gt;</comment>
