        Determine the expected type as the returned type of the method. If the return type is a List it will return the generic element type instead of a List.
        Parameters:

        method - Method
        Returns:

      • determineOperationType

        protected static Class determineOperationType​(Class resource,
                                                      Method method)
      • findMethodsByAnnotation

        public static List<Method> findMethodsByAnnotation​(Class objClass,
                                                           Class<? extends Annotation> annotationType)
        Finds methods for the given annotation It first finds all public member methods of the class or interface represented by objClass, including those inherited from superclasses and superinterfaces. It then loops through these methods searching for a single Annotation of annotationType, traversing its super methods if no annotation can be found on the given method itself.
        Parameters:
        objClass - - the class
        annotationType - - the annotation to find
        Returns:
        - the List of Method or an empty List
