Hello!
I am trying to write a program that finds and processes all invoke instructions
in a class file. My idea is to write something like this:
public static void main(String[] args) throws Exception {
ClassParser parser = new ClassParser(args[0]);
JavaClass jclcass = parser.parse();
Method[] amethod = jclcass.getMethods();
for (int i = 0 ; i < amethod.length ; i++) {
Code code = amethod[i].getCode();
InstructionList instrlist = MAGIG(code);
Instruction[] ainstr = instrlist.getInstructions();
for (int j = 0 ; j < ainstr.length ; j++) {
if (ainstr[j] instanceof InvokeInstruction) {
...
}
}
}
}
I have not been able to figure out how to write the method MAGIC()
which takes a Code instance and returns the set of instructions
(in the form of an InstructionList) contained in that byte code chunk.
I could try to copy the code found in Utility.codeToString() but before
I do that I would like to know if there is a better (== easier) way.
Thanks,
Lars
