Class RefactorPipeline

java.lang.Object
  at.dms.kjc.sir.lowering.partition.RefactorPipeline

public class RefactorPipeline
extends Object

This class is for refactoring pipelines. All methods in this class are written in an immutable way. Calling them does not mutate the arguments, or the parents of the arguments. (This is to facilitate their use in partitioning. !!! NOTE that this implies that, if you're trying to replace a stream in the stream graph, you'll need to do this manually after return from the method.

Method Detail

addHierarchicalChild

public static SIRPipeline addHierarchicalChild(SIRPipeline pipe,
                                               int first,
                                               int last)

Returns a new pipeline that is like

pipe

but replaces children at indices first...last with a pipeline that contains those children.

addHierarchicalChildren

public static SIRPipeline addHierarchicalChildren(SIRPipeline pipe,
                                                  PartitionGroup partition)

Given a pipeline

pipe

and a partitioning

partition

of its children, returns a new pipeline that has all the elements of each partition factored into their own pipelines.
