OutputTypeConfigurable (Flink : Streaming Java 1.18.1-cp5 API)

All Known Implementing Classes:

AbstractUdfStreamOperator, AsyncWaitOperator, BatchCoBroadcastWithKeyedOperator, BatchCoBroadcastWithNonKeyedOperator, BatchGroupedReduceOperator, CoBroadcastWithKeyedOperator, CoBroadcastWithNonKeyedOperator, CollectSinkOperator, ContinuousFileReaderOperator, CoProcessOperator, CoStreamFlatMap, CoStreamMap, EvictingWindowOperator, FromElementsFunction, IntervalJoinOperator, KeyedCoProcessOperator, KeyedProcessOperator, LegacyKeyedCoProcessOperator, LegacyKeyedProcessOperator, ProcessOperator, StreamFilter, StreamFlatMap, StreamGroupedReduceOperator, StreamMap, StreamSink, StreamSource, WindowOperator
```
@PublicEvolving
public interface OutputTypeConfigurable<OUT>
```
Stream operators can implement this interface if they need access to the output type information at StreamGraph generation. This can be useful for cases where the output type is specified by the returns method and, thus, after the stream operator has been created.

void setOutputType(org.apache.flink.api.common.typeinfo.TypeInformation<OUT> outTypeInfo,
                   org.apache.flink.api.common.ExecutionConfig executionConfig)
```
    Is called by the org.apache.flink.streaming.api.graph.StreamGraph#addOperator(Integer, String, StreamOperator, TypeInformation, TypeInformation, String) method when the StreamGraph is generated. The method is called with the output TypeInformation which is also used for the StreamTask output serializer.
    
    Parameters:
    
    outTypeInfo - Output type information of the StreamTask
    
    executionConfig - Execution configuration
