      • forName

        public static java.lang.Class<?> forName​(java.lang.String className)
        Tries to load the specified class using the context ClassLoader or if none, than from the default ClassLoader. This method differs from the standard class loading methods in that it does not throw an exception if the class is not found but returns null instead.
        Parameters:
        className - the class name to be loaded.
        Returns:
        the class or null if the class is not found.
      • findDeclaredFactoryMethods

        public static java.util.List<ConstructorOrMethod> findDeclaredFactoryMethods​(java.lang.Class<?> cls,
                                                                                     IAnnotationFinder finder)

        Parameters:
        cls - The class to search for the @Factory annotation.
        finder - The finder (JDK 1.4 or JDK 5.0+) use to search for the annotation.
