Method Detail

fetchPropositions

public Cons fetchPropositions(Cons pattern)

fetchInstance

public Stella_Object fetchInstance(Stella_Object name)

Description copied from class: ObjectStore

Fetch the instance identified by name (a string or symbol) from store and return it as an appropriate logic object. This needs to be appropriately specialized on actual OBJECT-STORE implementations.

Overrides:

fetchInstance in class ObjectStore

Returns:

Stella_Object

fetchRelation

public NamedDescription fetchRelation(Stella_Object name)

Description copied from class: ObjectStore

Fetch the relation identified by name (a string or symbol) from store and return it as a named description. This needs to be appropriately specialized on actual OBJECT-STORE implementations.

Overrides:

fetchRelation in class ObjectStore

Returns:

NamedDescription

closedPersistentStoreP

public static boolean closedPersistentStoreP(PersistentStore self)

closePersistentStore

public void closePersistentStore()
