Interface StorageConfiguration

All Known Implementing Classes:

BdbStorageConfiguration, CacheStorageConfiguration, FileBackedCachingStorageConfiguration, InMemoryStorageConfiguration, MysqlStorageConfiguration, ReadOnlyStorageConfiguration, ViewStorageConfiguration

public interface StorageConfiguration

An abstraction that represents the shared resources of a persistence engine. This could include file handles, db connection pools, caches, etc. For example for BDB it holds the various environments, for jdbc it holds a connection pool reference This should be called StorageEngineFactory but that would leave us with the indignity of having a StorageEngineFactoryFactory to handle the mapping of store type => factory. And we can't have that.

Method Summary

void	close() Close the storage configuration
StorageEngine<ByteArray,byte[],byte[]>	getStore(StoreDefinition storeDef, RoutingStrategy strategy) Get an initialized storage implementation
java.lang.String	getType() Get the type of stores returned by this configuration
void	update(StoreDefinition storeDef) Update the storage configuration at runtime
