WindowOperation (trino-parser 389 API)

java.lang.Object
- io.trino.sql.tree.Node
- - io.trino.sql.tree.Expression
  - - io.trino.sql.tree.WindowOperation

```
public class WindowOperation
extends Expression
```
Represents a call over a window:
```
     classifier OVER (...)
 
```
There are two types of window calls supported in Trino: - function calls - row pattern measures This class captures row pattern measures only. A function call over a window is represented as `FunctionCall` having a `Window` member. // TODO refactor `FunctionCall` so that it does not contain `Window`, and instead represent a windowed function call as `WindowOperation`
