Class GsonNotificationCallback<T>

java.lang.Object

com.google.api.client.googleapis.notifications.TypedNotificationCallback<T>

com.google.api.client.googleapis.notifications.json.JsonNotificationCallback<T>

com.google.api.client.googleapis.notifications.json.gson.GsonNotificationCallback<T>

Type Parameters:

T - Type of the data contained within a notification

All Implemented Interfaces:

UnparsedNotificationCallback, Serializable

@Beta
public abstract class GsonNotificationCallback<T>
extends JsonNotificationCallback<T>

Beta
A TypedNotificationCallback which uses an JSON content encoding with GsonFactory.getDefaultInstance().

Must NOT be implemented in form of an anonymous class as this will break serialization.

Implementation should be thread-safe.

Example usage:

  static class MyNotificationCallback
      extends GsonNotificationCallback <ListResponse > {

    private static final long serialVersionUID = 1L;

     @Override
    protected void onNotification(
        StoredChannel channel, TypedNotification <ListResponse > notification) {
      ListResponse content = notification.getContent();
      switch (notification.getResourceState()) {
        case ResourceStates.SYNC:
          break;
        case ResourceStates.EXISTS:
          break;
        case ResourceStates.NOT_EXISTS:
          break;
      }
    }

     @Override
    protected Class <ListResponse > getDataClass() throws IOException {
      return ListResponse.class;
    }
  }
