Package com.google.appengine.spi

Support for alternate implementations of Google App Engine services. This package is not intended for use by application code.

If, for example, vendor X wanted to provide an alternate implementation of the DatastoreService, they would have to provide an implementation of IDatastoreServiceFactory that returns their implementation for DatastoreService.

Factory implementations are acquired using a FactoryProvider registered with ServiceFactoryFactory. These providers are typically discovered using ServiceLoader; see ServiceFactoryFactory for details.

This package includes the utility (ServiceProvider for inserting the appropriate "service" entries into a jar file.
