Method Details

save

DeferredSaver save()

Start a deferred save command chain. Allows you to save (or re-save) entity objects. Note that all command chain objects are immutable.

Saves do NOT cascade; if you wish to save an object graph, you must save each individual entity.

A quick example: ofy().defer().save().entities(e1, e2, e3);

All command objects are immutable; this method returns a new object rather than modifying the current command object.

Returns:

the next step in the immutable command chain.

delete

DeferredDeleter delete()

Start a deferred delete command chain. Lets you delete entities or keys.

Deletes do NOT cascade; if you wish to delete an object graph, you must delete each individual entity.

A quick example: ofy().defer().delete().entities(e1, e2, e3);

All command objects are immutable; this method returns a new object rather than modifying the current command object.

Returns:

the next step in the immutable command chain.
