AsyncFunctionRunner (Flink : Table : Runtime 1.19.2-cp2 API)

java.lang.Object
- org.apache.flink.api.common.functions.AbstractRichFunction
- - org.apache.flink.streaming.api.functions.async.RichAsyncFunction<org.apache.flink.table.data.RowData,org.apache.flink.table.data.RowData>
  - - org.apache.flink.table.runtime.operators.calc.async.AsyncFunctionRunner

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.streaming.api.functions.async.AsyncFunction<org.apache.flink.table.data.RowData,org.apache.flink.table.data.RowData>
```
public class AsyncFunctionRunner
extends org.apache.flink.streaming.api.functions.async.RichAsyncFunction<org.apache.flink.table.data.RowData,org.apache.flink.table.data.RowData>
```
Async function runner for AsyncScalarFunction, which takes the generated function, instantiates it, and then calls its lifecycle methods.
