Examples of javassist.CtClass.writeFile()

javassist.CtClass.writeFile()
Writes a class file represented by this CtClass object in the current directory. Once this method is called, further modifications are not possible any more. @see #debugWriteFile()

        CtClass cc = loader.get("javassist.bytecode.StackMapTest$C4");
        MethodInfo mi = cc.getDeclaredMethod("foo").getMethodInfo();
        mi.rebuildStackMapForME(loader);
        CodeIterator ci = mi.getCodeAttribute().iterator();
        ci.insertGap(0, 7);
        cc.writeFile();
        Object t1 = make(cc.getName());
        assertEquals(6, invoke(t1, "test"));
    }


    public static class C4 {
