<DD><B>Description copied from interface: <CODE><A HREF="../../../mondrian/olap/type/Type.html#usesDimension(mondrian.olap.Dimension, boolean)">Type</A></CODE></B></DD>
<DD>Returns whether this type contains a given dimension.<p/>

 For example:
 <ul>
 <li><code>DimensionType([Gender])</code> uses only the
     <code>[Gender]</code> dimension.</li>
 <li><code>TupleType(MemberType([Gender]), MemberType([Store]))</code>
     uses <code>[Gender]</code>  and <code>[Store]</code>
     dimensions.</li>
 </ul><p/>

 The <code>definitely</code> parameter comes into play when the
 dimensional information is incomplete. For example, when applied to
 <code>TupleType(MemberType(null), MemberType([Store]))</code>,
 <code>usesDimension([Gender], false)</code> returns true because it
 is possible that the expression returns a member of the
 <code>[Gender]</code> dimension; but
 <code>usesDimension([Gender], true)</code> returns true because it
 is possible that the expression returns a member of the
 <code>[Gender]</code> dimension.

<DD><B>Description copied from interface: <CODE><A HREF="../../../mondrian/olap/type/Type.html#computeCommonType(mondrian.olap.type.Type, int[])">Type</A></CODE></B></DD>
<DD>Returns a Type which is more general than this and the given Type.
 The type returned is broad enough to hold any value of either type,
 but no broader. If there is no such type, returns null.

 <p>Some examples:<ul>
 <li>The common type for StringType and NumericType is ScalarType.
 <li>The common type for NumericType and DecimalType(4, 2) is
     NumericType.
 <li>DimensionType and NumericType have no common type.
 </ul></p>

 <p>If <code>conversionCount</code> is not null, implicit conversions
 such as HierarchyType to DimensionType are considered; the parameter
 is incremented by the number of conversions performed.

 <p>Some examples:<ul>
 <li>The common type for HierarchyType(hierarchy=Time.Weekly)
     and LevelType(dimension=Time), if conversions are allowed, is
     HierarchyType(dimension=Time).
 </ul>

 <p>One use of common types is to determine the types of the arguments
 to the <code>Iif</code> function. For example, the call

 <blockquote><code>Iif(1 > 2, [Measures].[Unit Sales], 5)</code></blockquote>

 has type ScalarType, because DecimalType(-1, 0) is a subtype of
 ScalarType, and MeasureType can be converted implicitly to ScalarType.
