<div class="block">An expression formed by a call to an operator with zero or more expressions
as operands.
<p>Operators may be binary, unary, functions, special syntactic constructs
like <code>CASE ... WHEN ... END</code>, or even internally generated
constructs like implicit type conversions. The syntax of the operator is
really irrelevant, because row-expressions (unlike
<a href="../sql/SqlNode.html" title="class in org.apache.calcite.sql"><code>SQL expressions</code></a>)
do not directly represent a piece of source code.
<p>It's not often necessary to sub-class this class. The smarts should be in
the operator, rather than the call. Any extra information about the call can
often be encoded as extra arguments. (These don't need to be hidden, because
no one is going to be generating source code from this tree.)</p></div>
