| Fn | () | constructor |
public function Fn(name:String, ... args)Creates a new Fn (function) operator.
Parametersname:String — the name of the function. This should map to an entry
in the static function table.

public override function clone():ExpressionCreates a cloned copy of the expression. Recursively clones any sub-expressions.
ReturnsExpression —
the cloned expression.
