public class SesameBackendCrdClcCnf
extends SesameBackendWithConfidence

Like a SesameBackendCrdClc that interprets the confidence value of received events before storing them. If the confidence is greater than the threshold passed to this class in the constructor or setThreshold, the event will be stored unchanged as in SesameBackend. Otherwise, only statements having the event as subject will be stored, but not reified statements about its subject nor object. Example: An "event1" with "subject2" "predicate3" and "object4" with enough confidence will result in having the statements in the store: "event1" "hasSubject" "subject2", "event1" "hasPredicate" "predicate3", "event1" "hasObject" "object4", "subject2" "predicate3" "object4" But if the confidence is below the threshold, the last reified statement is not stored.
