Assoc

a unidirectional association, or "assoc", between an entity and an aggregate root. the left side of the association - that is, the holder of the Assoc instance - is known as the associator. the right side of the association is the associatee.

there are basically two kinds of associations that you have to understand. an unpersisted assoc is one in which the associatee has not been persisted. in this case, an attempt to persist the associator will cascade persist the associatee.

a persisted assoc is one in which the associatee has already been persisted. it may or may not have already been loaded in to program memory, and calling retrieve or persisted or get may well trigger a database lookup.

Abstract Value Members

abstract val associateeTypeKey: TypeKey[R]

a type key for the associatee
abstract def isPersisted: Boolean

true whenever the assoc is with a persisted entity
abstract def retrieve: Future[PState[R]]

retrieves a persisted assoc.
retrieves a persisted assoc. if the associatee has not been loaded into memory, calling this method will result in a database lookup

Exceptions thrown
longevity.exceptions.subdomain.AssocIsUnpersistedException whenever the assoc is not persisted
abstract def unpersisted: R

retrieves an unpersisted associatee from the assoc
retrieves an unpersisted associatee from the assoc

Exceptions thrown
longevity.exceptions.subdomain.AssocIsPersistedException whenever the assoc is persisted
