centraldogma-0.42.0

New features

• You can fork a Watcher and use it to get notified only when the specific part of the file is changed.

  CentralDogma client = ...
  // watcher is get notified when "ab.json" file is changed.
  Watcher<JsonNode> watcher = client.fileWatcher("myProject", "myRepo", 
                                                 Query.ofJson("/ab.json"));
  // aChild is get notified only when the property "/a" is changed.
  Watcher<String> aChild = watcher.newChild(jsonNode -> jsonNode.at("/a").asText());
  aChild.watch((rev, a) -> {
      // This will be triggered if '/a' is changed.
  });
  
  // bChild is get notified only when the property "/a" is changed.
  Watcher<String> bChild = watcher.newChild(jsonNode -> jsonNode.at("/b").asText());
  bChild.watch((rev, b) -> {
      // This will be triggered if '/b' is changed.
  });

• You can make separate Watchers to achieve the same behavior.

  Watcher<String> aWatcher = client.fileWatcher("myProject", "myRepo", 
                                                Query.ofJsonPath("/ab.json", "$.a"));
  aWatcher.watch((rev, a) -> {
      // This will be triggered if '/a' is changed.
  });
  Watcher<String> bWatcher = client.fileWatcher("myProject", "myRepo", 
                                                Query.ofJsonPath("/ab.json", "$.b"));
  bWatcher.watch((rev, b) -> {
      // This will be triggered if '/b' is changed.
  });

  • However, these Watchers make separate watch requests to the server meanwhile the previous example makes only one watch request and notifies according to the Function.
