Method Details

load

@Deprecated
T load(Object naturalIdToLoad,
 NaturalIdLoadOptions options,
 SharedSessionContractImplementor session)

Deprecated.

(since 7.3) : use load(Object, Options, SharedSessionContractImplementor) instead.

Perform the load of the entity by its natural-id

Parameters:

naturalIdToLoad - 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 efficient

options - The options to apply to the load operation

session - The session into which the entity is being loaded

load

T load(Object naturalIdToLoad,
 NaturalIdLoader.Options options,
 SharedSessionContractImplementor session)

Perform the load of the entity by its natural-id

Parameters:

naturalIdToLoad - The normalized form of the natural-id.

options - The options to apply to the load operation

session - The session into which the entity is being loaded

resolveNaturalIdToId

Object resolveNaturalIdToId(Object naturalIdValue,
 SharedSessionContractImplementor session)

Resolve the id from natural-id value

resolveIdToNaturalId

Object resolveIdToNaturalId(Object id,
 SharedSessionContractImplementor session)

Resolve the natural-id value(s) from an id
