Examples of org.apache.derby.io.WritableStorageFactory

org.apache.derby.io.WritableStorageFactory
This interface extends StorageFactory to provide read/write access to storage.
The database engine will call this interface's methods from its own privilege blocks.
Each WritableStorageFactory instance may be concurrently used by multiple threads.
