接口 SetupableStreamOperator<OUT>

类型参数:

OUT - The output type of the operator

所有已知实现类:

AbstractStreamOperator, AbstractUdfStreamOperator, AsyncWaitOperator, CoBroadcastWithKeyedOperator, CoBroadcastWithNonKeyedOperator, ContinuousFileReaderOperator, CoProcessOperator, CoStreamFlatMap, CoStreamMap, EvictingWindowOperator, ExtractTimestampsOperator, GenericWriteAheadSink, IntervalJoinOperator, KeyedCoProcessOperator, KeyedProcessOperator, LegacyKeyedCoProcessOperator, LegacyKeyedProcessOperator, ProcessOperator, QueryableAppendingStateOperator, QueryableValueStateOperator, SourceReaderOperator, StreamFilter, StreamFlatMap, StreamGroupedFold, StreamGroupedReduce, StreamMap, StreamProject, StreamSink, StreamSource, TimestampsAndPeriodicWatermarksOperator, TimestampsAndPunctuatedWatermarksOperator, WindowOperator

已过时。

This class is deprecated in favour of using StreamOperatorFactory and it's StreamOperatorFactory.createStreamOperator(org.apache.flink.streaming.runtime.tasks.StreamTask<?, ?>, org.apache.flink.streaming.api.graph.StreamConfig, org.apache.flink.streaming.api.operators.Output<org.apache.flink.streaming.runtime.streamrecord.StreamRecord<OUT>>) and passing the required parameters to the Operator's constructor in create method.

@Deprecated
 @PublicEvolving
public interface SetupableStreamOperator<OUT>

Stream operators can implement this interface if they need access to the context and the output.
