translateForBatchInternal

protected Collection<Integer> translateForBatchInternal(BroadcastStateTransformation<IN1,IN2,OUT> transformation,
                                                        TransformationTranslator.Context context)

从类复制的说明: SimpleTransformationTranslator

Translates a given Transformation to its runtime implementation for BATCH-style execution.

指定者:

translateForBatchInternal 在类中 SimpleTransformationTranslator<OUT,BroadcastStateTransformation<IN1,IN2,OUT>>

参数:

transformation - The transformation to be translated.

context - The translation context.

返回:

The ids of the "last" StreamNodes in the transformation graph corresponding to this transformation. These will be the nodes that a potential following transformation will need to connect to.

translateForStreamingInternal

protected Collection<Integer> translateForStreamingInternal(BroadcastStateTransformation<IN1,IN2,OUT> transformation,
                                                            TransformationTranslator.Context context)

从类复制的说明: SimpleTransformationTranslator

Translates a given Transformation to its runtime implementation for STREAMING-style execution.

指定者:

translateForStreamingInternal 在类中 SimpleTransformationTranslator<OUT,BroadcastStateTransformation<IN1,IN2,OUT>>

参数:

transformation - The transformation to be translated.

context - The translation context.

返回:

The ids of the "last" StreamNodes in the transformation graph corresponding to this transformation. These will be the nodes that a potential following transformation will need to connect to.
