 <div class="block">A <code>SqlLiteral</code> is a constant. It is, appropriately, immutable.

  <p>How is the value stored? In that respect, the class is somewhat of a black
  box. There is a <a href="#getValue()"><code>getValue()</code></a> method which returns the value as an
  object, but the type of that value is implementation detail, and it is best
  that your code does not depend upon that knowledge. It is better to use
  task-oriented methods such as <a href="SqlNode.html#toSqlString(org.apache.calcite.sql.SqlDialect)"><code>SqlNode.toSqlString(SqlDialect)</code></a> and
  <a href="#toValue()"><code>toValue()</code></a>.</p>

  <p>If you really need to access the value directly, you should switch on the
  value of the <a href="#typeName"><code>typeName</code></a> field, rather than making assumptions about
  the runtime type of the <a href="#value"><code>value</code></a>.</p>

  <p>The allowable types and combinations are:
