Method Summary

de.fub.bytecode.generic.MethodGen	createCloneMethod(java.lang.String className, de.fub.bytecode.generic.MethodGen mg) Creates an intial copy of an existing method which is to be overloaded and returns the MethodGen object of the created method
int	createMethodInvocation(de.fub.bytecode.generic.MethodGen mg, de.fub.bytecode.generic.Type[] consArgTypes, de.fub.bytecode.generic.MethodGen consmg)
de.fub.bytecode.generic.MethodGen	deleteMethodParameter1(de.fub.bytecode.generic.MethodGen mg) Second approach of overloading method, deleting a parameter and then removing all the instructions that access the deleted parameter
de.fub.bytecode.generic.MethodGen	deleteMethodParameter2(de.fub.bytecode.generic.MethodGen mg) Third approach of overloading method, deleting a parameter and then creating a new variable to replicate the deleted parameter
void	deleteTargeterRange(de.fub.bytecode.generic.MethodGen mg, de.fub.bytecode.generic.InstructionList instrList, int index) Deletes the instructions within 2 consecutive targeters in which the instruction referenced by 'index' lies
de.fub.bytecode.generic.MethodGen	insertMethodParameter(de.fub.bytecode.generic.MethodGen mg) First approach of overloading method, inserting a new parameter
void	reInitializeParameters(de.fub.bytecode.generic.MethodGen mg) Re-initializes the parameters of the newly created method
boolean	remVecfreqUpdatesInThreshold(int numVectors, int currVecIndex, VectorUpdateCtrl vecObj, de.fub.bytecode.generic.MethodGen mg) This method checks that the sideEffects of overloading a method is within a particular threshold limit

Method Detail

remVecfreqUpdatesInThreshold

public boolean remVecfreqUpdatesInThreshold(int numVectors,
                                            int currVecIndex,
                                            VectorUpdateCtrl vecObj,
                                            de.fub.bytecode.generic.MethodGen mg)

This method checks that the sideEffects of overloading a method is within a particular threshold limit

deleteMethodParameter2

public de.fub.bytecode.generic.MethodGen deleteMethodParameter2(de.fub.bytecode.generic.MethodGen mg)

Third approach of overloading method, deleting a parameter and then creating a new variable to replicate the deleted parameter

deleteMethodParameter1

public de.fub.bytecode.generic.MethodGen deleteMethodParameter1(de.fub.bytecode.generic.MethodGen mg)

Second approach of overloading method, deleting a parameter and then removing all the instructions that access the deleted parameter

public de.fub.bytecode.generic.MethodGen createCloneMethod(java.lang.String className,
                                                           de.fub.bytecode.generic.MethodGen mg)

Creates an intial copy of an existing method which is to be overloaded and returns the MethodGen object of the created method

reInitializeParameters

public void reInitializeParameters(de.fub.bytecode.generic.MethodGen mg)

Re-initializes the parameters of the newly created method

insertMethodParameter

public de.fub.bytecode.generic.MethodGen insertMethodParameter(de.fub.bytecode.generic.MethodGen mg)
