AsyncWindowOperator.WindowContext (Flink : Runtime 2.1.0 API)

java.lang.Object
- org.apache.flink.runtime.asyncprocessing.operators.windowing.AsyncWindowOperator.WindowContext

All Implemented Interfaces:

Serializable, InternalAsyncWindowFunction.InternalWindowContext

Enclosing class:

AsyncWindowOperator<K,IN,ACC,OUT,W extends Window>
```
public class AsyncWindowOperator.WindowContext
extends Object
implements InternalAsyncWindowFunction.InternalWindowContext
```
A utility class for handling ProcessWindowFunction invocations. This can be reused by setting the key and window fields. No internal state must be kept in the WindowContext.
