| <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="../../../../org/apache/calcite/sql/SqlLiteral.html#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="../../../../org/apache/calcite/sql/SqlNode.html#toSqlString-org.apache.calcite.sql.SqlDialect-"><code>SqlNode.toSqlString(SqlDialect)</code></a> and |
| <a href="../../../../org/apache/calcite/sql/SqlLiteral.html#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="../../../../org/apache/calcite/sql/SqlLiteral.html#typeName"><code>typeName</code></a> field, rather than making assumptions about |
| the runtime type of the <a href="../../../../org/apache/calcite/sql/SqlLiteral.html#value"><code>value</code></a>.</p> |
