All known Subclasses: org.mandarax.zkb.AbstractOPS,
| ObjectPersistencyService | | public interface ObjectPersistencyService (Code) | | Interface describing an object persisteny service (OPS).
An object persisteny service is responsible for saving objects stored in a kind of
map (associating object uris and objects) to a stream, and recovering the map from
a stream. This is to support knowledge base storage: while knowledge base objects
such as rules and facts are stored in an xml file, the objects referenced are stored
separately as one big map. This is to benefit from existing technologies like
serialization.
The interface is similar to an JNDI context - most implementations will work with
maps associating names and serialized object references.
