Class CachingDatastoreServiceFactory

java.lang.Object

com.googlecode.objectify.cache.CachingDatastoreServiceFactory

public class CachingDatastoreServiceFactory
extends Object

A convenience class with factory methods to create caching versions of DatastoreService and AsyncDatastoreService. These are just shortcuts for common cases - do not be afraid to use the constructors of CachingDatastoreService or CachingAsyncDatastoreService to create an interface tailored exactly to your caching needs.
