 <div class="block">Enumerates the possible types of <a href="SqlNode.html" title="class in org.apache.calcite.sql"><code>SqlNode</code></a>.

  <p>The values are immutable, canonical constants, so you can use Kinds to
  find particular types of expressions quickly. To identity a call to a common
  operator such as '=', use <a href="SqlNode.html#isA(java.util.Set)"><code>SqlNode.isA(java.util.Set&lt;org.apache.calcite.sql.SqlKind&gt;)</code></a>:</p>

  <blockquote>
  exp.<a href="SqlNode.html#isA(java.util.Set)"><code>isA</code></a>(<a href="#EQUALS"><code>EQUALS</code></a>)
  </blockquote>

  <p>Only commonly-used nodes have their own type; other nodes are of type
  <a href="#OTHER"><code>OTHER</code></a>. Some of the values, such as <a href="#SET_QUERY"><code>SET_QUERY</code></a>, represent
  aggregates.</p>

  <p>To quickly choose between a number of options, use a switch statement:</p>

  <blockquote>
  <pre>switch (exp.getKind()) {
  case <a href="#EQUALS"><code>EQUALS</code></a>:
      ...;
  case <a href="#NOT_EQUALS"><code>NOT_EQUALS</code></a>:
      ...;
  default:
      throw new AssertionError("unexpected");
  }</pre>
  </blockquote>

  <p>Note that we do not even have to check that a <code>SqlNode</code> is a
  <a href="SqlCall.html" title="class in org.apache.calcite.sql"><code>SqlCall</code></a>.</p>

  <p>To identify a category of expressions, use <code>SqlNode.isA</code> with
  an aggregate SqlKind. The following expression will return <code>true</code>
  for calls to '=' and '&gt;=', but <code>false</code> for the constant '5', or
  a call to '+':</p>

  <blockquote>
  <pre>exp.isA(<a href="#COMPARISON"><code>SqlKind.COMPARISON</code></a>)</pre>
  </blockquote>

  <p>RexNode also has a <code>getKind</code> method; <code>SqlKind</code> values are
  preserved during translation from <code>SqlNode</code> to <code>RexNode</code>, where
  applicable.</p>

  <p>There is no water-tight definition of "common", but that's OK. There will
  always be operators that don't have their own kind, and for these we use the
  <code>SqlOperator</code>. But for really the common ones, e.g. the many places
  where we are looking for <code>AND</code>, <code>OR</code> and <code>EQUALS</code>, the enum
  helps.</p>

  <p>(If we were using Scala, <a href="SqlOperator.html" title="class in org.apache.calcite.sql"><code>SqlOperator</code></a> would be a case
  class, and we wouldn't need <code>SqlKind</code>. But we're not.)</p></div>
