| ZKBManager | | public class ZKBManager implements LogCategories(Code) | | Persistency manager supporting the serialization of knowledge bases. The
functionality is similar to the XBKManager. However, there are the following
differences:
- The ZKB Manager serializes the knowledge base as XML, similiar to XKB.
It uses modified XKB drivers to achieve this.
- Objects (in particular objects used in constant terms) are not XML
serialized with the knowledge base. Instead, they are referenced by (string)
uris.
- Objects are serialized using a separate
ObjectPersistncyService (OPS). The idea is to re-use existing
services such as binary and (JDK-) XML serialization.
- The two streams (knowledge base and objects (resources)) are zipped
together,
Public methods are synchronized in order to ensure the consistency of the OPS
used (added in 3.2).
