Window (Flink : 2.0-preview1 API)

java.lang.Object
- org.apache.flink.table.runtime.operators.window.Window

All Implemented Interfaces:

Comparable<Window>

Direct Known Subclasses:

CountWindow, TimeWindow
```
public abstract class Window
extends Object
implements Comparable<Window>
```
A Window is a grouping of elements into finite buckets. Windows have a maximum timestamp which means that, at some point, all elements that go into one window will have arrived.
Subclasses should implement equals() and hashCode() so that logically same windows are treated the same.
