Annotation Type Persistent

    • Element Detail

      • persistenceModifier

        PersistenceModifier persistenceModifier
        Modifier for this field. This is normally not specified, and the defaults are used, or the @Transactional or @NotPersistent annotation is specified directly on the member. One possible use for specifying persistenceModifier is for embedded instances in which a member is not persistent but in the non-embedded instances the member is persistent. Note that it is not portable to specify a member to be not persistent in the non-embedded case and persistent in the embedded usage.

        javax.jdo.annotations.PersistenceModifier.UNSPECIFIED
