Provides a framework for static code analysis based on the asm.tree package.
Basic usage:
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. ... } }
