Method Detail

translateForBatchInternal

protected Collection<Integer> translateForBatchInternal(SideOutputTransformation<OUT> transformation,
                                                        TransformationTranslator.Context context)

Description copied from class: SimpleTransformationTranslator

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

Specified by:

translateForBatchInternal in class SimpleTransformationTranslator<OUT,SideOutputTransformation<OUT>>

Parameters:

transformation - The transformation to be translated.

context - The translation context.

Returns:

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(SideOutputTransformation<OUT> transformation,
                                                            TransformationTranslator.Context context)

Description copied from class: SimpleTransformationTranslator

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

Specified by:

translateForStreamingInternal in class SimpleTransformationTranslator<OUT,SideOutputTransformation<OUT>>

Parameters:

transformation - The transformation to be translated.

context - The translation context.

Returns:

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.
