Method Details

getEntityDescriptor

EntityPersister getEntityDescriptor()

Get the descriptor for the type of entity being initialized

getConcreteDescriptor

EntityPersister getConcreteDescriptor(Data data)

getConcreteDescriptor

default EntityPersister getConcreteDescriptor(RowProcessingState rowProcessingState)

getTargetInstance

default Object getTargetInstance(Data data)

API Note:

Calling this method is only valid from the time Initializer.resolveKey(InitializerData) has been called until Initializer.finishUpRow(InitializerData) has been called for the currently processing row

getTargetInstance

default Object getTargetInstance(RowProcessingState rowProcessingState)

resolveEntityKeyOnly

default @Nullable EntityKey resolveEntityKeyOnly(RowProcessingState rowProcessingState)

getEntityIdentifier

@Nullable Object getEntityIdentifier(Data data)

getEntityIdentifier

default @Nullable Object getEntityIdentifier(RowProcessingState rowProcessingState)

resetResolvedEntityRegistrations

default void resetResolvedEntityRegistrations(RowProcessingState rowProcessingState)

Resets the resolved entity registrations by i.e. removing EntityHolder.
