                               ome.model.internal.Details newDetails)
        asks BasicSecuritySystem to create a new managed Details based on the previous state of this entity. If the previous state is null (see ticket:3929) then throw an exception.
        Parameters:
        entity - IObject to be updated
        currentState - the possibly changed field data for this entity
        previousState - the field data as seen in the db
        idx - the index of Details in the state arrays.

      • log

      • evaluateLinkages

        public ome.model.internal.Details evaluateLinkages​(ome.model.IObject changedObject)
        Checks the details of the objects which the given object links to in order to guarantee that linkages are valid. In the case of a non-specific UID or GID, then the Details object returned by this method can be used as the basis for unknown user/group. This method is called during save and update since this is the only time that new entity references can be created.
        Parameters:
        changedObject - new or updated entity which may reference other entities which then require locking. Nulls are tolerated but do nothing.

      • neededRight

        The default right need for a linkage is Permissions.Right.WRITE. If however, this is only an annotation or only a viewing, then less permission is needed.
        Parameters:
        changedClass - the changed class
        linkedClass - the linked class
        Returns:
        the right that is needed

        Deprecated.
        responsible for guaranteeing that external info is not modified by any users, including root. This does not apply to the "client concern" fields which can be modified after the fact.
        Parameters:
        privileged - if the user is privileged
        obj - the model object
        previousDetails - details representing the known DB state
        currentDetails - details representing the user request (UNTRUSTED)
        newDetails - details from the current context. Holder for the merged Permissions
        Returns:
        true if the Permissions of newDetails are changed.
