| Interface | Description |
|---|---|
| Value |
An immutable symbolic value for semantic interpretation of bytecode.
|
| Class | Description |
|---|---|
| Analyzer<V extends Value> |
A semantic bytecode analyzer.
|
| BasicInterpreter |
An
Interpreter for BasicValue values. |
| BasicValue |
A
Value that is represented by its type in a seven types type system. |
| BasicVerifier |
An extended
BasicInterpreter that checks that bytecode instructions
are correctly used. |
| Frame<V extends Value> |
A symbolic execution stack frame.
|
| Interpreter<V extends Value> |
A semantic bytecode interpreter.
|
| SimpleVerifier |
An extended
BasicVerifier that performs more precise verifications. |
| SourceInterpreter |
An
Interpreter for SourceValue values. |
| SourceValue |
A
Value that is represented by its type in a two types type system. |
| Exception | Description |
|---|---|
| AnalyzerException |
Thrown if a problem occurs during the analysis of a method.
|
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.
