Interface ScanningClassification

public interface ScanningClassification

Maps Classifiers to Subscribers and selects which Subscriber should receive which publication through scanning through all Subscribers through the matches(classifier, event) method

Note: the compareClassifiers and compareSubscribers must together form an absolute ordering (think java.util.Comparator.compare)

Method Summary

int	compareClassifiers(ScanningClassification a, ScanningClassification b) Provides a total ordering of Classifiers (think java.util.Comparator.compare)
int	compareSubscribers(ScanningClassification a, ScanningClassification b) Provides a total ordering of Subscribers (think java.util.Comparator.compare)
boolean	matches(ScanningClassification classifier, ScanningClassification event) Returns whether the specified Classifier matches the specified Event
void	publish(ScanningClassification event)
void	publish(ScanningClassification event, ScanningClassification subscriber) Publishes the specified Event to the specified Subscriber
boolean	subscribe(ScanningClassification subscriber, ScanningClassification to)
java.util.concurrent.ConcurrentSkipListSet<scala.Tuple2<java.lang.Object,java.lang.Object>>	subscribers()
void	unsubscribe(ScanningClassification subscriber)
boolean	unsubscribe(ScanningClassification subscriber, ScanningClassification from)
