| Provides a framework for static code analysis based on the asm.tree package. |
| </p> |
| |
| <p> |
| Basic usage: |
| </p> |
| |
| <pre> |
| 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. |
| ... |
| } |
| } |
| </pre> |
