Examples of org.apache.lucene.gdata.storage.Storage

org.apache.lucene.gdata.storage.Storage
A interface every storage implementation must provide to access the Storage. It describes all access methodes needed to store, retrieve and look up data stored in the Storage component. This interface acts as a Facade to hide the storage implementation from the user.
This could also act as a proxy for a remote storage. It also removes any restrictions from custom storage implementations.
