Interface DynamicStatistics

All Known Implementing Classes:

ExtensibleDynamicEvaluationStatistics

@Experimental
public interface DynamicStatistics

Interface to support evaluation statistics that keep their own internal estimates and need to be notified of added or removed statements.

Method Summary

Modifier and Type	Method	Description
void	add(ExtensibleStatement statement)
void	remove(ExtensibleStatement statement)
void	removeByQuery(Resource subj, IRI pred, Value obj, boolean inferred, Resource... contexts)
double	staleness(long expectedSize)

Method Details

add

void add(ExtensibleStatement statement)

remove

void remove(ExtensibleStatement statement)

removeByQuery

void removeByQuery(Resource subj,
 IRI pred,
 Value obj,
 boolean inferred,
 Resource... contexts)

staleness

double staleness(long expectedSize)

Parameters:

expectedSize -

Returns:

1 if stale, 0 if not stale, 0.5 if 50% stale. Seen as, given a random statement (that has either been added, or removed), what is the probability that the statistics will return an incorrect result?
