Class ORecordTrackedSet

java.lang.Object

java.util.AbstractCollection<OIdentifiable>

com.orientechnologies.orient.core.db.record.ORecordTrackedSet

All Implemented Interfaces:

ORecordElement, OTrackedMultiValue<OIdentifiable,OIdentifiable>, Iterable<OIdentifiable>, Collection<OIdentifiable>, Set<OIdentifiable>

Direct Known Subclasses:

ORecordLazySet

public class ORecordTrackedSet
extends AbstractCollection<OIdentifiable>
implements Set<OIdentifiable>, OTrackedMultiValue<OIdentifiable,OIdentifiable>, ORecordElement

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.
