Provides a framework for static code analysis based on the asm.tree package.
Basic usage:
ClassReader cr = new ClassReader(bytecode);
ClassNode cn = new ClassNode();
cr.accept(cn, ClassReader.SKIP_DEBUG);
List methods = cn.methods;
for (int i = 0; i < methods.size(); ++i) {
MethodNode method = (MethodNode) methods.get(i);
if (method.instructions.size() > 0) {
Analyzer a = new Analyzer(new BasicInterpreter());
a.analyze(cn.name, method);
Frame[] frames = a.getFrames();
// Elements of the frames arrray now contains info for each instruction
// from the analyzed method. BasicInterpreter creates BasicValue, that
// is using simplified type system that distinguishes the UNINITIALZED,
// INT, FLOAT, LONG, DOUBLE, REFERENCE and RETURNADDRESS types.
