方法详细资料

createStreamOperator

public <O extends StreamOperator<OUT>> O createStreamOperator(StreamOperatorParameters<OUT> parameters)

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>

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

getStreamOperatorClass

public Class<? extends StreamOperator> getStreamOperatorClass(ClassLoader classLoader)

从接口复制的说明: StreamOperatorFactory

Returns the runtime class of the stream operator.

指定者:

getStreamOperatorClass 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>
