Re: Doubt regarding reference access

Hi Eshwari,
AFAIK, you can look at the InstructionHandle to find out what sort of 
instruction is in it.
System.out.println is most likely to be an InvokeInstruction of which you 
can find out what parameters were passed to it by calling getArgumentTypes.
The following code illustrates this:
InstructionHandle iHnd;
Instruction ii;
ii = (Instruction)iHnd.getInstruction();
if (ii instanceof InvokeInstruction) {
argTypes = ((InvokeInstruction)ii).getArgumentTypes(cpg);
.....
If the statement is of the type str = "dfdfd";
The Instruction would be an instance of PUTSTATIC or PUTFIELD depending on 
whether str is a static variable or an instance variable.
