Method Detail

mapToMapFromEntity

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

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

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

void mapToEntityFromMap(EnversService enversService,
                        Object obj,
                        Map data,
                        Object primaryKey,
                        AuditReaderImplementor versionsReader,
                        Number revision)

Maps properties from the given map to the given object.

Parameters:

enversService - The EnversService.

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

List<PersistentCollectionChangeData> mapCollectionChanges(SessionImplementor session,
                                                          String referencingPropertyName,
                                                          PersistentCollection newColl,
                                                          Serializable oldColl,
                                                          Serializable id)

Maps collection changes.

Parameters:

session - The current session.

referencingPropertyName - Name of the field, which holds the collection in the entity.

newColl - New collection, after updates.

oldColl - Old collection, before updates.

id - Id of the object owning the collection.

Returns:

List of changes that need to be performed on the persistent store.

mapModifiedFlagsToMapFromEntity

void mapModifiedFlagsToMapFromEntity(SessionImplementor session,
                                     Map<String,Object> data,
                                     Object newObj,
                                     Object oldObj)

mapModifiedFlagsToMapForCollectionChange

void mapModifiedFlagsToMapForCollectionChange(String collectionPropertyName,
                                              Map<String,Object> data)
