How Would I Retrieve An Embedded Entity With Repeated Properties Using Datastore Java Client

I created entities on datastore using the AppEngine SDK's python APIs and I'd like to retrieve them on Google Cloud Dataflow (Java). The entity's structure is something like this:

Solution 1:

Ok, got it. This is how I enabled it:

staticclassEmbeddedStringExtractorextendsDoFn<Entity, String> {
  @OverridepublicvoidprocessElement(ProcessContext c) {
    Map<String, Value> main_entity_map = DatastoreHelper.getPropertyMap(c.element());
    List<Value> embedded_entity_values = entity.get("embedded_entity").getListValueList();

      for (Valueembedded_entity_value: embedded_entity_values){
          Entity embedded_entity = embedded_entity_value.getEntityValue();
          Map<String, Value> embedded_map = DatastoreHelper.getPropertyMap(embedded_entity);
          String embedded_name = DatastoreHelper.getString(embedded_map.get("name"));
      }

    // And then just c.output whatever you need.

   }
}

Just needed to get used to the Java APIs.
