      • cookClasses

        public void cookClasses()
      • orderDefinitions

        protected List<UserDefinedJavaClassDef> orderDefinitions​(List<UserDefinedJavaClassDef> definitions)
        This method oders the classes by sorting all the normal classes by alphabetic order and then sorting all the transaction classes by alphabetical order. This makes the resolution of classes deterministic by type and then by class name.
        Parameters:
        definitions - - Unorder list of user defined classes
        Returns:
        - Ordered list of user defined classes
