Thing Scope and Data

When a thing is registered on Kii Cloud, a dedicated thing scope is created for it. New buckets and KiiObjects will be defined within this scope (See Thing scope for the overview of the thing scope).

The way you manage buckets and KiiObjects in a thing scope is the same as that of other scopes. See "Managing Data" (Android, iOS, JavaScript) to learn more.

Here are examples of creating a new KiiObject in a thing scope.

Android

  • try {
      // Instantiate a thing by vendor thing ID.
      KiiThing thing = KiiThing.loadWithVendorThingID("rBnvSPOXBDF9r29GJeGS");
    
      // Create a bucket.
      KiiBucket thingBucket = thing.bucket("thing_bucket");
    
      // Create a KiiObject.
      KiiObject object = thingBucket.object();
    
      // Set a key-value pair.
      object.set("geo", new GeoPoint(35.710036, 139.811046));
    
      // Save the KiiObject.
      object.save();
    } catch (AppException e) {
      // Handle the error.
    } catch (IOException e) {
      // Handle the error.
    }
  • // Instantiate a thing by vendor thing ID.
    KiiThing.loadWithVendorThingID("rBnvSPOXBDF9r29GJeGS", new KiiCallback<KiiThing>() {
      @Override
      public void onComplete(KiiThing result, Exception e) {
        if (e != null) {
          // Handle the error.
          return;
        }
    
        // Create a bucket.
        KiiBucket thingBucket = result.bucket("thing_bucket");
    
        // Create a KiiObject.
        KiiObject object = thingBucket.object();
    
        // Set a key-value pair.
        object.set("geo", new GeoPoint(35.710036, 139.811046));
    
        // Save the KiiObject.
        object.save(new KiiObjectCallBack() {
          @Override
          public void onSaveCompleted(int token, KiiObject object, Exception exception) {
            if (exception != null) {
              // Handle the error.
              return;
            }
          }
        });
      }
    });

Swift 3:

  • let thing : KiiThing
    
    do{
      // Instantiate a thing by vendor thing ID.
      thing = try KiiThing.loadSynchronous(withVendorThingID: "rBnvSPOXBDF9r29GJeGS")

    // Create a KiiObject.
    let object = thingBucket.createObject()
    
    // Set a key-value pair.
    object.setGeoPoint(KiiGeoPoint(latitude: 35.710036, andLongitude: 139.811046), forKey: "geo")
    
    do {
      // Save the KiiObject.
      try object.saveSynchronous()
    } catch let error as NSError {
      // Handle the error.
      return
    }
  • // Instantiate a thing by vendor thing ID.
    KiiThing.load(withVendorThingID: "rBnvSPOXBDF9r29GJeGS") { (thing , error) -> Void in
      if error != nil {
        // Handle the error.
        return
      }
    
      // Create a bucket.
      let thingBucket = thing!.bucket(withName: "thing_bucket")
