Class Nonvirtualize

java.lang.Object
  harpoon.Analysis.Transformation.MethodMutator<Quad>
      harpoon.Analysis.Quads.Nonvirtualize

All Implemented Interfaces:

Serializable

public class Nonvirtualize
extends MethodMutator<Quad>

Nonvirtualize uses a FinalMap to change virtual method invocations to non-virtual invocations, where this is safe. Virtual method invocation is slower than non-virtual invocation.

Nonvirtualize(HCodeFactory hcf, FinalMap fm)
Creates a Nonvirtualize using the given FinalMap.

Nonvirtualize(HCodeFactory hcf, FinalMap fm, ClassHierarchy ch)
Creates a Nonvirtualize using the given FinalMap; the given ClassHierarchy is used to avoid devirtualizing calls to uncallable methods (which artificially inflates the class hierarchy size).
