<div class="block">Helper method to determine a
<a href="../core/Values.html" title="class in org.apache.calcite.rel.core"><code>Values</code></a>'s collation.
<p>We actually under-report the collations. A Values with 0 or 1 rows - an
edge case, but legitimate and very common - is ordered by every permutation
of every subset of the columns.
<p>So, our algorithm aims to:<ul>
<li>produce at most N collations (where N is the number of columns);
<li>make each collation as long as possible;
<li>do not repeat combinations already emitted -
if we've emitted <code>(a, b)</code> do not later emit <code>(b, a)</code>;
<li>probe the actual values and make sure that each collation is
consistent with the data
</ul>
<p>So, for an empty Values with 4 columns, we would emit
<code>(a, b, c, d), (b, c, d), (c, d), (d)</code>.</div>
