方法详细资料

of

public static <OUT> SimpleOperatorFactory<OUT> of(StreamOperator<OUT> operator)

Create a SimpleOperatorFactory from existed StreamOperator.

getOperator

public StreamOperator<OUT> getOperator()

createStreamOperator

public <T extends StreamOperator<OUT>> T createStreamOperator(StreamTask<?,?> containingTask,
                                                              StreamConfig config,
                                                              Output<StreamRecord<OUT>> output)

从接口复制的说明: StreamOperatorFactory

Create the operator. Sets access to the context and the output.

指定者:

createStreamOperator 在接口中 StreamOperatorFactory<OUT>

setChainingStrategy

public void setChainingStrategy(ChainingStrategy strategy)

从接口复制的说明: StreamOperatorFactory

Set the chaining strategy for operator factory.

指定者:

setChainingStrategy 在接口中 StreamOperatorFactory<OUT>

getChainingStrategy

public ChainingStrategy getChainingStrategy()

从接口复制的说明: StreamOperatorFactory

Get the chaining strategy of operator factory.

指定者:

getChainingStrategy 在接口中 StreamOperatorFactory<OUT>

isStreamSource

public boolean isStreamSource()

从接口复制的说明: StreamOperatorFactory

Is this factory for StreamSource.

指定者:

isStreamSource 在接口中 StreamOperatorFactory<OUT>

isOutputTypeConfigurable

public boolean isOutputTypeConfigurable()

从接口复制的说明: StreamOperatorFactory

If the stream operator 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.

指定者:

isOutputTypeConfigurable 在接口中 StreamOperatorFactory<OUT>

setOutputType

public void setOutputType(org.apache.flink.api.common.typeinfo.TypeInformation<OUT> type,
                          org.apache.flink.api.common.ExecutionConfig executionConfig)

从接口复制的说明: StreamOperatorFactory

Is called by the StreamGraph.addOperator(java.lang.Integer, java.lang.String, java.lang.String, org.apache.flink.streaming.api.operators.StreamOperatorFactory<OUT>, org.apache.flink.api.common.typeinfo.TypeInformation<IN>, org.apache.flink.api.common.typeinfo.TypeInformation<OUT>, java.lang.String) method when the StreamGraph is generated. The method is called with the output TypeInformation which is also used for the StreamTask output serializer.

指定者:

setOutputType 在接口中 StreamOperatorFactory<OUT>

参数:

type - Output type information of the StreamTask

executionConfig - Execution configuration

isInputTypeConfigurable

public boolean isInputTypeConfigurable()

从接口复制的说明: StreamOperatorFactory

If the stream operator need to be configured with the data type they will operate on.

指定者:

isInputTypeConfigurable 在接口中 StreamOperatorFactory<OUT>

setInputType

public void setInputType(org.apache.flink.api.common.typeinfo.TypeInformation<?> type,
                         org.apache.flink.api.common.ExecutionConfig executionConfig)

从接口复制的说明: StreamOperatorFactory
