Class ORecordLazySet

java.lang.Object

java.util.AbstractCollection<OIdentifiable>

com.orientechnologies.orient.core.db.record.ORecordLazySet

All Implemented Interfaces:

OSizeable, OAutoConvertToRecord, ODetachable, ORecordElement, ORecordLazyMultiValue, OTrackedMultiValue<OIdentifiable,OIdentifiable>, OIdentityChangeListener, Iterable<OIdentifiable>, Collection<OIdentifiable>, Set<OIdentifiable>

public class ORecordLazySet
extends AbstractCollection<OIdentifiable>
implements Set<OIdentifiable>, OTrackedMultiValue<OIdentifiable,OIdentifiable>, ORecordElement, ORecordLazyMultiValue, OIdentityChangeListener

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

Internals:

• stores new records in a separate IdentityHashMap to keep underlying list (delegate) always ordered and minimizing sort operations
