Class OTrackedMap<T>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<Object,T>

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

All Implemented Interfaces:

ORecordElement, OTrackedMultiValue<Object,T>, Serializable, Cloneable, Map<Object,T>

Direct Known Subclasses:

ORecordLazyMap

public class OTrackedMap<T>
extends LinkedHashMap<Object,T>
implements ORecordElement, OTrackedMultiValue<Object,T>, Serializable

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

Reverts all operations that were performed on collection and return original collection state.

Specified by:

returnOriginalState in interface OTrackedMultiValue<Object,T>

Parameters:

multiValueChangeEvents - List of operations that were performed on collection.

Returns:

Original collection state.
