Modifier and Type	Method	Description
void	arcCreated(Object nodeId, Object targetNodeId, ArcId arcId)	Notifies implementing object that a new arc was created between two nodes.
void	arcDeleted(Object nodeId, Object targetNodeId, ArcId arcId)	Notifies implementing object that an arc between two nodes was deleted.
DataRow	getCachedSnapshot(ObjectId oid)	Returns a snapshot for ObjectId from the underlying snapshot cache.
DataContext	getContext()
DataRowStore	getDataRowCache()	Returns a DataRowStore associated with this ObjectStore.
ObjectId	getFlattenedId(ObjectId objectId, CayennePath path)
Collection<ObjectId>	getFlattenedIds(ObjectId objectId)
Map<CayennePath, ObjectId>	getFlattenedPathIdMap(ObjectId objectId)
Object	getNode(Object nodeId)	Returns a registered Persistent objects or null of no object exists for the ObjectId.
Iterator<Persistent>	getObjectIterator()	Returns an iterator over the registered objects.
DataRow	getSnapshot(ObjectId oid)	Returns a snapshot for ObjectId from the underlying snapshot cache.
boolean	hasChanges()	Returns true if there are any modified, deleted or new objects registered with this ObjectStore, false otherwise.
void	markFlattenedPath(ObjectId objectId, CayennePath path, ObjectId id)	Mark that flattened path for object has data row in DB.
void	nodeCreated(Object nodeId)	Notifies implementing object that a new node was created in the graph.
void	nodeIdChanged(Object nodeId, Object newId)	Does nothing.
void	nodePropertyChanged(Object nodeId, String property, Object oldValue, Object newValue)	Records dirty object snapshot.
void	nodeRemoved(Object nodeId)	Notifies implementing object that a node was removed from the graph.
List<Persistent>	objectsInState(int state)	Return a subset of registered objects that are in a certain persistence state.
void	objectsRolledBack()	Reverts changes to all stored uncomitted objects.
void	objectsUnregistered(Collection objects)	Evicts a collection of Persistent objects from the ObjectStore, invalidates the underlying cache snapshots.
void	postprocessAfterCommit(GraphDiff parentChanges)	Internal unsynchronized method to process objects state after commit.
Collection<Object>	registeredNodes()	Returns all registered Persistent objects.
int	registeredObjectsCount()	Returns a number of objects currently registered with this ObjectStore.
void	registerNode(Object nodeId, Object nodeObject)	"Registers" a graph node, usually storing the node in some internal map using its id as a key.
void	setContext(DataContext context)
void	snapshotsChanged(SnapshotEvent event)	SnapshotEventListener implementation that processes snapshot change event, updating Persistent objects that have the changes.
Object	unregisterNode(Object nodeId)	"Unregisters" a graph node, forgetting any information associated with nodeId.

setDataRowCache

public void setDataRowCache(DataRowStore dataRowCache)

Description copied from class: ObjectStore

Sets parent DataRowStore. Registers to receive SnapshotEvents if the cache is configured to allow ObjectStores to receive such events.
