A new entity, net.sourceforge.symba.versioning.Endurant, has been created within the net.sourceforge.symba namespace within the FuGE-OM. To examine this entity, please open the "Endurant" class diagram within the SyMBA-FuGEv1.mdzip file stored in the symba-mda/src/main/uml directory.
The Endurant entity is a concrete instance of Describable, as all entities utilizing the FuGE-OM are meant to be. However, in practical terms, none of the Describable aspects of the Endurant class are currently in use within SyMBA. The only attribute of this entity is an "identifier" attribute. Within SyMBA, this is always an LSID. Each Identifiable object within the FuGE-OM now has an association (named "endurant") to one of these objects. The Endurant is a grouping object that links different Identifiables of the same concrete class.
net.sourceforge.symba.service.SymbaEntityService is a service class similar in design to net.sourceforge.fuge.service.EntityService . Its purpose is to liase with the persistence layer, and perform additional functions that require connections to the database. While EntityService provides basic functions relating to saving, creating and updating objects in the database, the SymbaEntityService is more geared to complex or specialized search queries over the database. This class is described in the SymbaEntityService class diagram in the UML.
net.sourceforge.symba.service.SymbaEntityServiceException is the exception class that is thrown if there is any problem when running methods from SymbaEntityService. This class is described in the SymbaEntityService class diagram in the UML.
