Class DispatchTreeTransformation

java.lang.Object
  harpoon.Analysis.Transformation.MethodMutator
      harpoon.Analysis.Quads.DispatchTreeTransformation

All Implemented Interfaces:

Serializable

public class DispatchTreeTransformation
extends MethodMutator

DispatchTreeTransformation replaces dynamic dispatch call sites with TYPESWITCHes leading to static dispatch calls. Given proper optimization of the TYPESWITCH test, this should speed up dispatch.

Constructor Summary

DispatchTreeTransformation(HCodeFactory parent, ClassHierarchy ch)
Creates a DispatchTreeTransformation.

Method Summary

protected HCodeAndMaps	cloneHCode(HCode hc, HMethod newmethod) Override this method if you do not want the mutatable HCode to be a straight clone of the original HCode: for example, if the input HCodes were QuadSSI and you wanted to clone them into QuadRSSIs before mutating.
protected String	mutateCodeName(String codeName) Override this method to change the codename which this MethodMutator's codefactory reports.
protected HCode	mutateHCode(HCodeAndMaps input) Override this method to effect transformations on split methods.

Method Detail

mutateHCode

protected HCode mutateHCode(HCodeAndMaps input)

Description copied from class: MethodMutator

Override this method to effect transformations on split methods.

Overrides:

mutateHCode in class MethodMutator

cloneHCode

protected HCodeAndMaps cloneHCode(HCode hc,
                                  HMethod newmethod)

Description copied from class: MethodMutator

Override this method if you do not want the mutatable HCode to be a straight clone of the original HCode: for example, if the input HCodes were QuadSSI and you wanted to clone them into QuadRSSIs before mutating. By default, this method returns hc.clone(newmethod).

Overrides:

cloneHCode in class MethodMutator

mutateCodeName

protected String mutateCodeName(String codeName)

Description copied from class: MethodMutator

Override this method to change the codename which this MethodMutator's codefactory reports.

Overrides:

mutateCodeName in class MethodMutator
