Package com.google.appengine.spi Description

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 com.google.appengine.api.datastore.IDatastoreServiceFactory that returns their implementation for com.google.appengine.api.datastore.DatastoreService.

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

This package include utilities (ServiceProvider and ServiceProviderProcessor) for inserting the appropriate "service" entries into a jar file.
