      static java.lang.reflect.Type getSuperType​(java.lang.reflect.Type subType, java.lang.Class<?> rawSuperType)
      Get the super type for a type in its super type chain, which has a raw class that matches the specified class.
      static java.lang.reflect.Type getTypeArgument​(java.lang.reflect.Type type)
      Get the generic argument, or the first if the type has more than one.
      static java.lang.reflect.Type[] getTypeArguments​(java.lang.reflect.Type type)

      static boolean isTypeOrSubTypeOf​(java.lang.reflect.Type subType, java.lang.reflect.Type superType)

      static boolean restResponseTypeExpectsBody​(java.lang.reflect.ParameterizedType restResponseReturnType)
      Returns whether the rest response expects to have any body (by checking if the body parameter type is set to Void, in which case no body is expected).
