<DD><B>Description copied from interface: <CODE><A HREF="../../../mondrian/calc/Calc.html#dependsOn(mondrian.olap.Dimension)">Calc</A></CODE></B></DD>
<DD>Returns whether this expression depends upon a given dimension.

 <p>If it does not depend on the dimension, then re-evaluating the
 expression with a different member of this context must produce the
 same answer.<p/>

 Some examples:<ul>

 <li>The expression
 <blockquote><code>[Measures].[Unit Sales]</code></blockquote>
 depends on all dimensions except <code>[Measures]</code>.

 <li>The boolean expression
 <blockquote><code>([Measures].[Unit Sales],
 [Time].[1997]) &gt; 1000</code></blockquote>
 depends on all dimensions except [Measures] and [Time].

 <li>The list expression
 <blockquote><code>Filter([Store].[USA].Children,
 [Measures].[Unit Sales] &lt; 50)</code></pre></blockquote>
 depends upon all dimensions <em>except</em> [Store] and [Measures].
 How so? Normally the scalar expression would depend upon all dimensions
 except [Measures], but the <code>Filter</code> function sets the [Store]
 context before evaluating the scalar expression, so it is not inherited
 from the surrounding context.
