类 CacheTransformationTranslator.NoOpStreamOperator<T>

java.lang.Object

org.apache.flink.streaming.api.operators.AbstractStreamOperator<T>

org.apache.flink.streaming.runtime.translators.CacheTransformationTranslator.NoOpStreamOperator<T>

类型参数:

T - The output type of the operator, which is the type of the cached intermediate dataset as well.

所有已实现的接口:

Serializable, org.apache.flink.api.common.state.CheckpointListener, Input<T>, KeyContext, OneInputStreamOperator<T,T>, SetupableStreamOperator<T>, StreamOperator<T>, StreamOperatorStateHandler.CheckpointedStreamOperator

封闭类:

CacheTransformationTranslator<OUT,T extends CacheTransformation<OUT>>

public static class CacheTransformationTranslator.NoOpStreamOperator<T>
extends AbstractStreamOperator<T>
implements OneInputStreamOperator<T,T>

The CacheTransformationTranslator.NoOpStreamOperator acts as a dummy sink so that the upstream can produce the intermediate dataset to be cached.
