| Provides a framework for static code analysis based on the asm.tree package. |
| </p> |
| |
| <p> |
| Basic usage: |
| </p> |
| |
| <pre> |
| ClassReader classReader = new ClassReader(bytecode); |
| ClassNode classNode = new ClassNode(); |
| classReader.accept(classNode, ClassReader.SKIP_DEBUG); |
| |
| for (MethodNode method : classNode.methods) { |
| if (method.instructions.size() > 0) { |
| Analyzer analyzer = new Analyzer(new BasicInterpreter()); |
| analyzer.analyze(classNode.name, method); |
| Frame[] frames = analyzer.getFrames(); |
| // Elements of the frames array 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> |
