Class AsyncFunctionRunner

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.
