com.orientechnologies.orient.core.db.record.OTrackedSet<T>

All Implemented Interfaces:

ORecordElement, OTrackedMultiValue<T,T>, Serializable, Cloneable, Iterable<T>, Collection<T>, Set<T>

public class OTrackedSet<T>
extends HashSet<T>
implements ORecordElement, OTrackedMultiValue<T,T>, Serializable

Implementation of Set bound to a source ORecord object to keep track of changes. This avoid to call the makeDirty() by hand when the set is changed.
