public static void reset()

weave

public void weave()
           throws KilimException

Throws:

KilimException

private void accept(org.objectweb.asm.ClassVisitor cv)

toStringArray

static String[] toStringArray(List list)

addClassInfo

void addClassInfo(ClassInfo ci)

getClassInfos

public List<ClassInfo> getClassInfos()

needsWeaving

boolean needsWeaving(MethodFlow mf)

needsWeaving

boolean needsWeaving()

createStateClass

String createStateClass(ValInfoList valInfoList)

Create a custom class (structure) to hold the state. The name of the state reflects the numbers of the various VMtypes in valInfoList. class kilim.SO2IJ3 reflects a class that stores two Objects one Integer and 3 longs.

            class kilim.SO2IJ3 extends kilim.State {
               public Object f1, f2;
               public int f3;
               public long f4, f5, f6;
            } 
 

If there's no data to store, we use the kilim.State class directly to store the basic amount of data necessary to restore the stack.

private String makeClassName(int[] numByType)

isInterface

boolean isInterface()

getSAMWeaver

SAMweaver getSAMWeaver(String owner,
 String methodName,
 String desc,
