Method Detail

load

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

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

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
