Examples of com.db4o.ObjectContainer

com.db4o.ObjectContainer
the interface to a db4o database, stand-alone or client/server.

The ObjectContainer interface provides methods to store, query and delete objects and to commit and rollback transactions.

An ObjectContainer can either represent a stand-alone database or a connection to a {@link Db4o#openServer(String,int) db4o server}.

An ObjectContainer also represents a transaction. All work with db4o always is transactional. Both {@link #commit()} and{@link #rollback()} start new transactions immediately. For working against the same database with multiple transactions, open a db4o server with {@link Db4o#openServer(String,int)} and {@link ObjectServer#openClient() connect locally} or{@link Db4o#openClient(String,int,String,String) over TCP}. @see ExtObjectContainer ExtObjectContainer for extended functionality. @sharpen.ignore
