Method Detail

setChainingStrategy

public void setChainingStrategy(ChainingStrategy strategy)

Description copied from class: PhysicalTransformation

Sets the chaining strategy of this Transformation.

Specified by:

setChainingStrategy in class PhysicalTransformation<OutputT>

getTransitivePredecessors

public List<Transformation<?>> getTransitivePredecessors()

Description copied from class: Transformation

Returns all transitive predecessor Transformations of this Transformation. This is, for example, used when determining whether a feedback edge of an iteration actually has the iteration head as a predecessor.

Specified by:

getTransitivePredecessors in class Transformation<OutputT>

Returns:

The list of transitive predecessors.

getInputs

public List<Transformation<?>> getInputs()

Description copied from class: Transformation

Returns the transformations that are the immediate predecessors of the current transformation in the transformation graph.

Specified by:

getInputs in class Transformation<OutputT>

getChainingStrategy

@Nullable
public ChainingStrategy getChainingStrategy()

getInputStream

public DataStream<InputT> getInputStream()

getSink

public Sink<InputT> getSink()

getSinkOperatorsUidHashes

public CustomSinkOperatorUidHashes getSinkOperatorsUidHashes()
