| <blockquote><code> |

| 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. |
