Examples of BaseRecordManager

jdbm.recman.BaseRecordManager
This class manages records, which are uninterpreted blobs of data. The set of operations is simple and straightforward: you communicate with the class using long "rowids" and byte[] data blocks. Rowids are returned on inserts and you can stash them away someplace safe to be able to get back to them. Data blocks can be as long as you wish, and may have lengths different from the original when updating.
Operations are synchronized, so that only one of them will happen concurrently even if you hammer away from multiple threads. Operations are made atomic by keeping a transaction log which is recovered after a crash, so the operations specified by this interface all have ACID properties.
You identify a file by just the name. The package attaches .db for the database file, and .lg for the transaction log. The transaction log is synchronized regularly and then restarted, so don't worry if you see the size going up and down. @author Alex Boisvert @author Cees de Groot @version $Id: BaseRecordManager.java,v 1.8 2005/06/25 23:12:32 doomdark Exp $
