void	accept(InstructionVisitor insVisitor)
Instruction	execute(ThreadInfo ti) this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g.
int	getArgSize()
int	getByteCode()
protected ClassInfo	getClassInfo()

getClassInfo

protected ClassInfo getClassInfo()

getByteCode

public int getByteCode()

Specified by:

getByteCode in class Instruction

getStaticElementInfo

public StaticElementInfo getStaticElementInfo()

getClassObjectRef

public int getClassObjectRef()

execute

public Instruction execute(ThreadInfo ti)

Description copied from class: Instruction

this is the real workhorse returns next instruction to enter in this thread <2do> it's unfortunate we roll every side effect into this method, because it diminishes the value of the 'executeInstruction' notification: all insns that require some sort of late binding (InvokeVirtual, GetField, ..) are not yet fully analyzable (e.g. the callee of InvokeVirtuals is not known yet), putting the burden of duplicating the related code of enter() in the listener. It would be better if we factor this 'prepareExecution' out of enter()

Specified by:

execute in class Instruction

getInvokedMethod
