String getSlotSharingGroup()

Returns the slot sharing group for the given transformation.

getDefaultBufferTimeout

long getDefaultBufferTimeout()

Returns the default buffer timeout to be used.

getGraphGeneratorConfig

ReadableConfig getGraphGeneratorConfig()

Retrieves additional configuration for the graph generation process.

transform

Collection<Integer> transform(Transformation<?> transformation)

Transforms the transformation and updates the current stream graph.
