    • injectCallbackRegistry

      public void injectCallbackRegistry(CallbackRegistry callbackRegistry)
      Description copied from interface: CallbackRegistryConsumer
      Injection of the CallbackRegistry
      Specified by:
      injectCallbackRegistry in interface CallbackRegistryConsumer
      Parameters:
      callbackRegistry - The CallbackRegistry

    • saveWithRequestedId

      protected Object saveWithRequestedId(Object entity, Object requestedId, String entityName, C context, EventSource source)
      Prepares the save call using the given requested id.
      Parameters:
      entity - The entity to be saved.
      requestedId - The id to which to associate the entity.
      entityName - The name of the entity being saved.
      context - Generally cascade-specific information.
      source - The session which is the source of this save event.
      Returns:
      The id used to save the entity.

    • saveWithGeneratedId

      protected Object saveWithGeneratedId(Object entity, String entityName, C context, EventSource source, boolean requiresImmediateIdAccess)
      Prepares the save call using a newly generated id.
      Parameters:
      entity - The entity to be saved
      entityName - The entity-name for the entity to be saved
      context - Generally cascade-specific information.
      source - The session which is the source of this save event.
      requiresImmediateIdAccess - does the event context require access to the identifier immediately after execution of this method (if not, post-insert style id generators may be postponed if we are outside a transaction).
      Returns:
      The id used to save the entity; may be null depending on the type of id generator used and the requiresImmediateIdAccess value

    • performSave

      protected Object performSave(Object entity, Object id, EntityPersister persister, boolean useIdentityColumn, C context, EventSource source, boolean delayIdentityInserts)
      Prepares the save call by checking the session caches for a pre-existing entity and performing any lifecycle callbacks.
      Parameters:
      entity - The entity to be saved.
      id - The id by which to save the entity.
      persister - The entity's persister instance.
      useIdentityColumn - Is an identity column being used?
      context - Generally cascade-specific information.
      source - The session from which the event originated.
      delayIdentityInserts - Should the identity insert be delayed?
      Returns:
      The id used to save the entity; may be null depending on the type of id generator used and on delayIdentityInserts

    • performSaveOrReplicate

      protected Object performSaveOrReplicate(Object entity, EntityKey key, EntityPersister persister, boolean useIdentityColumn, C context, EventSource source, boolean delayIdentityInserts)
      Performs all the actual work needed to save an entity (well to get the save moved to the execution queue).
      Parameters:
      entity - The entity to be saved
      key - The id to be used for saving the entity (or null, in the case of identity columns)
      persister - The entity's persister instance.
      useIdentityColumn - Should an identity column be used for id generation?
      context - Generally cascade-specific information.
      source - The session which is the source of the current event.
      delayIdentityInserts - Should the identity insert be delayed?
      Returns:
      The id used to save the entity; may be null depending on the type of id generator used and the requiresImmediateIdAccess value

    • getMergeMap

      protected Map<Object,Object> getMergeMap(C anything)

    • isVersionIncrementDisabled

      protected boolean isVersionIncrementDisabled()
      After the save, will te version number be incremented if the instance is modified?
      Returns:
      True if the version will be incremented on an entity change after save; false otherwise.

    • visitCollectionsBeforeSave

      protected boolean visitCollectionsBeforeSave(Object entity, Object id, Object[] values, Type[] types, EventSource source)

    • substituteValuesIfNecessary

      protected boolean substituteValuesIfNecessary(Object entity, Object id, Object[] values, EntityPersister persister, SessionImplementor source)
      Perform any property value substitution that is necessary (interceptor callback, version initialization...)
      Parameters:
      entity - The entity
      id - The entity identifier
      values - The snapshot entity state
      persister - The entity persister
      source - The originating session
      Returns:
      True if the snapshot state changed such that reinjection of the values into the entity is required.

    • cascadeBeforeSave

      protected void cascadeBeforeSave(EventSource source, EntityPersister persister, Object entity, C context)
