<div class="block">Writes a SQL representation of this node to a writer.
<p>The <code>leftPrec</code> and <code>rightPrec</code> parameters give
us enough context to decide whether we need to enclose the expression in
parentheses. For example, we need parentheses around "2 + 3" if preceded
by "5 *". This is because the precedence of the "*" operator is greater
than the precedence of the "+" operator.
<p>The algorithm handles left- and right-associative operators by giving
them slightly different left- and right-precedence.
<p>If <a href="SqlWriter.html#isAlwaysUseParentheses()"><code>SqlWriter.isAlwaysUseParentheses()</code></a> is true, we use
parentheses even when they are not required by the precedence rules.
<p>For the details of this algorithm, see <a href="SqlCall.html#unparse(org.apache.calcite.sql.SqlWriter,int,int)"><code>SqlCall.unparse(org.apache.calcite.sql.SqlWriter, int, int)</code></a>.</div>
