Needs to be public so that instrumented code can access it. ANY CHANGE IN THIS CLASS NEEDS TO BE SYNCHRONIZED WITH InstrumentMethod

Method Detail

getStack

public static Stack getStack()

pushMethodAndReserveSpace

public final void pushMethodAndReserveSpace(int entry,
                                            int numSlots)

Called before a method is called.

Parameters:

entry - the entry point in the method for resume

numSlots - the number of required stack slots for storing the state

popMethod

public final void popMethod()

Called at the end of a method. Undoes the effects of nextMethodEntry() and clears the dataObject[] array to allow the values to be GCed.

nextMethodEntry

public final int nextMethodEntry()

called at the begin of a method

Returns:

the entry point of this method

push

public static void push(int value,
                        Stack s,
                        int idx)

push

public static void push(float value,
                        Stack s,
                        int idx)

push

public static void push(long value,
                        Stack s,
                        int idx)

push

public static void push(double value,
                        Stack s,
                        int idx)

push

public static void push(Object value,
