getLoadable
public EntityMappingType getLoadable()
Description copied from interface:Loader
The value-mapping loaded by this loader- Specified by:
getLoadable
in interfaceEntityLoader
- Specified by:
getLoadable
in interfaceLoader
-
load
public T load(Object naturalIdValue, NaturalIdLoadOptions options, SharedSessionContractImplementor session)
Description copied from interface:NaturalIdLoader
Perform the load of the entity by its natural-id- Specified by:
load
in interfaceNaturalIdLoader<T>
- Parameters:
naturalIdValue
- The natural-id to load. One of 2 forms accepted: * Single-value - valid for entities with a simple (single-valued) natural-id * Map - valid for any natural-id load. The map is each value keyed by the attribute name that the value corresponds to. Even though this form is allowed for simple natural-ids, the single value form should be used as it is more efficientoptions
- The options to apply to the load operationsession
- The session into which the entity is being loaded
-
selectByNaturalId
protected <L> L selectByNaturalId(Object bindValue, NaturalIdLoadOptions options, BiFunction<TableGroup,LoaderSqlAstCreationState,DomainResult<?>> domainResultProducer, LoaderSqlAstCreationState.FetchProcessor fetchProcessor, Function<Boolean,Long> statementStartHandler, BiConsumer<Object,Long> statementCompletionHandler, SharedSessionContractImplementor session)
Perform a select, restricted by natural-id, based on `domainResultProducer` and `fetchProcessor`
-
applyNaturalIdRestriction
protected abstract void applyNaturalIdRestriction(Object bindValue, TableGroup rootTableGroup, Consumer<Predicate> predicateConsumer, BiConsumer<JdbcParameter,JdbcParameterBinding> jdbcParameterConsumer, LoaderSqlAstCreationState sqlAstCreationState, SharedSessionContractImplementor session)
Apply restriction necessary to match the given natural-id value. Should apply any predicates to `predicateConsumer` as well and any parameter / binding pairs
