| DatabasePersistence | | public class DatabasePersistence extends PersistencePluginAdapter implements PersistencePlugin(Code) | | This
PersistencePlugin saves blackboard objects in a
database. It saves and restores persistence deltas in RDB tables.
We store the deltas for each agent in a separate table named
after the agent: delta_<agentName>. The table has three columns:
seqno -- has an INTEGER delta sequence number
active -- has a CHAR indicating the kind of delta stored
x -- full delta (all data)
t -- incremental delta
a -- archive delta (full but not active)
f -- inactive incremental
The above codes were selected for backward compatibility with the
former t/f meaning active was true/false
data -- has a LONG RAW with the serialized data
