All Implemented Interfaces:

OSizeable, OAutoConvertToRecord, ODetachable, ORecordElement, ORecordLazyMultiValue, OTrackedMultiValue<Object,OIdentifiable>, Serializable, Cloneable, Map<Object,OIdentifiable>

public class ORecordLazyMap
extends OTrackedMap<OIdentifiable>
implements ORecordLazyMultiValue

Lazy implementation of LinkedHashMap. It's bound to a source ORecord object to keep track of changes. This avoid to call the makeDirty() by hand when the map is changed.

public Iterator<OIdentifiable> rawIterator()

Specified by:

rawIterator in interface ORecordLazyMultiValue

detach

public boolean detach()

Description copied from interface: ODetachable

Detaches the object.

Specified by:

detach in interface ODetachable
