Method Details

translateForBatchInternal

public Collection<Integer> translateForBatchInternal(OneInputTransformation<IN,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,OneInputTransformation<IN,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

public Collection<Integer> translateForStreamingInternal(OneInputTransformation<IN,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,OneInputTransformation<IN,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.
