Examples of javassist.CtClass

javassist.CtClass
An instance of CtClass represents a class. It is obtained from ClassPool. @see ClassPool#get(String)

        CtClass ctClass = findCtClass(AbstractFoo.class);


        CtClass[] interfaces = ctClass.getInterfaces();


        assertEquals(interfaces.length, 1);


        assertEquals(interfaces[0].getName(), FooInterface.class.getName());


        // In some cases, Java reflection on an abstract class implementing an interface
        // will show the interface methods as abstract methods on the class. This seems
        // to vary from JVM to JVM. I believe Javassist is more consistent here.


        CtMethod[] methods = ctClass.getDeclaredMethods();


        assertEquals(methods.length, 0);
