Method Details
-
entity
Asynchronously save a single entity in the datastore.
If the entity has a null Long id, the value will be autogenerated and populated on the entity object when the async operation completes. If you require this value, call now() on the result.
Puts do not cascade.
- Parameters:
entity
- must be a registered entity type- Returns:
- an asynchronous result. To force a synchronous save, call Result.now().
-
entities
Asynchronously save a batch of entities in the datastore.

Puts do not cascade.
- Parameters:
entities
- must be registered entity types- Returns:
- an asynchronous result. To force a synchronous save, call Result.now().

toEntity
Convert a POJO object to a native datastore Entity. This is like a save() operation but without actually saving the data to the datastore.- Parameters:
pojo
- must be an instance of a registered pojo entity type.- Returns:
- the native datastore Entity equivalent of the pojo; exactly what Objectify would save if you saved the POJO normally.
