Interface Store

All Known Implementing Classes:
DataSourceStore, FileStore, JDBCStore, StoreBase
public interface Store
A Store is the abstraction of a Catalina component that provides persistent storage and loading of Sessions and their associated user data. Implementations are free to save and load the Sessions to any media they wish, but it is assumed that saved Sessions are persistent across server or context restarts.
