Method Detail

mapToMapFromEntity

public boolean mapToMapFromEntity(SessionImplementor session,
                                  Map<String,Object> data,
                                  Object newObj,
                                  Object oldObj)

Description copied from interface: PropertyMapper

Maps properties to the given map, basing on differences between properties of new and old objects.

Specified by:

mapToMapFromEntity in interface PropertyMapper

Parameters:

session - The current session.

data - Data to map to.

newObj - New state of the entity.

oldObj - Old state of the entity.

Returns:

True if there are any differences between the states represented by newObj and oldObj.

mapToEntityFromMap

public void mapToEntityFromMap(AuditConfiguration verCfg,
                               Object obj,
                               Map data,

Description copied from interface: PropertyMapper

Maps properties from the given map to the given object.

Specified by:

mapToEntityFromMap in interface PropertyMapper

Parameters:

verCfg - Versions configuration.

obj - Object to map to.

data - Data to map from.

primaryKey - Primary key of the object to which we map (for relations)

versionsReader - VersionsReader for reading relations

revision - Revision at which the object is read, for reading relations

mapCollectionChanges

public List<PersistentCollectionChangeData> mapCollectionChanges(String referencingPropertyName,
                                                                 PersistentCollection newColl,
