How to implement a custom parser

[wuxiaochen1209]

In version 3.1.0, how should I define a custom parser final ServiceVersionResolver resolver = new ServiceVersionResolver() {      @Override      Public Service resolve(ServiceType type, SortedSet<? extends Service> services) {          // resolver logic; possibly ext. default logic          Return endpoint;      } }; withConfig(Config.newConfig().withResolver(resolver)) This example can't be used? Is there a specific implementation?
