Class CacheTransformationTranslator.IdentityStreamOperator<T>
- java.lang.Object
-
- org.apache.flink.streaming.api.operators.AbstractStreamOperator<T>
-
- org.apache.flink.streaming.runtime.translators.CacheTransformationTranslator.IdentityStreamOperator<T>
-
- Type Parameters:
T- The output type of the operator, which is the type of the cached intermediate * dataset as well.
- All Implemented Interfaces:
Serializable,org.apache.flink.api.common.state.CheckpointListener,Input<T>,KeyContext,KeyContextHandler,OneInputStreamOperator<T,T>,StreamOperator<T>,StreamOperatorStateHandler.CheckpointedStreamOperator,YieldingOperator<T>
- Enclosing class:
- CacheTransformationTranslator<OUT,T extends CacheTransformation<OUT>>
public static class CacheTransformationTranslator.IdentityStreamOperator<T> extends AbstractStreamOperator<T> implements OneInputStreamOperator<T,T>
TheCacheTransformationTranslator.IdentityStreamOperatoracts as a dummy source to consume cached intermediate dataset.- See Also:
