Examples of com.googlecode.objectify.Objectify

com.googlecode.objectify.Objectify

This is the main "business end" of Objectify. It lets you load, save, and delete your typed POJO entities.

{@code Objectify} instances are obtained by calling the static method {@code ObjectifyService.ofy()}. This method will always provide the correct {@code Objectify} instance for a given transactional context. You can runtransactions by calling {@code Objectify.transact()} or {@code Objectify.transactNew()}; calling {@code ObjectifyService.ofy()}within {@code Work.run()} will produce the correct {@code Objectify} instance associated with the correct transaction.
Objectify instances are immutable but they are NOT thread-safe. The instance contains a session cache of entities that have been loaded from the instance. You should never access an Objectify from more than one thread simultaneously.
