copied!<p><strong>Edit: This works only on concrete classes (the class to inspect has its own .class file). I changed the code below to reflect this. Until diving deeper into the ClassFileAnalyzer library to work with classes directly instead of reading them from a temporary file this limitation exists.</strong></p> <p>Following approach works for me:</p> <p>Download and import following libarary <a href="http://classfileanalyzer.javaseiten.de/" rel="nofollow noreferrer">ClassFileAnalyzer</a></p> <p>Add the following two static methods (Attention! getClussDump() needs a little modification for writing out the class file to a temporary file: I removed my code here because it's very special at this point):</p> <pre><code>public static String getClassDump(Class<?> c) throws Exception { String classFileName = c.getSimpleName() + ".class"; URL resource = c.getResource(classFileName); if (resource == null) { throw new RuntimeException("Works only for concreate classes!"); } String absolutePath = ...; // write to temp file and get absolute path ClassFile classFile = new ClassFile(absolutePath); classFile.parse(); Info infos = new Info(classFile, absolutePath); StringBuffer infoBuffer = infos.getInfos(); return infoBuffer.toString(); } public static <S extends List<Method>> S sortMethodsBySourceOrder(Class<?> c, S methods) throws Exception { String classDump = getClassDump(c); int index = classDump.indexOf("constant_pool_count:"); final String dump = classDump.substring(index); Collections.sort(methods, new Comparator<Method>() { public int compare(Method o1, Method o2) { Integer i1 = Integer.valueOf(dump.indexOf(" " + o1.getName() + lineSeparator)); Integer i2 = Integer.valueOf(dump.indexOf(" " + o2.getName() + lineSeparator)); return i1.compareTo(i2); }}); return methods; } </code></pre> <p>Now you can call the sortMethodsBySourceOrder with any List of methods (because sorting arrays is not very comfortable) and you will get the list back sorted. </p> <p>It works by looking at the class dumps constant pool which in turn can be determined by the library.</p> <p>Greetz, GHad</p>
