scouter.org.objectweb.asm.tree.analysis.package.html Maven / Gradle / Ivy
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.
