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

All Implemented Interfaces:

ORecordElement, OTrackedMultiValue<Integer,T>, Serializable, Cloneable, Iterable<T>, Collection<T>, List<T>, RandomAccess

Direct Known Subclasses:

ORecordTrackedList

public class OTrackedList<T>
extends ArrayList<T>
implements ORecordElement, OTrackedMultiValue<Integer,T>, Serializable

Implementation of ArrayList bound to a source ORecord object to keep track of changes for literal types. This avoid to call the makeDirty() by hand when the list is changed.
