| virtual void metadb_io_callback::on_changed_sorted | ( | metadb_handle_list_cref | p_items_sorted, | |

| ) | [pure virtual] |
Called when metadb contents change. (Or, one of display hook component requests display update).
- Parameters:
-
p_items_sorted List of items that have been updated. The list is always sorted by pointer value, to allow fast bsearch to test whether specific item has changed. p_fromhook Set to true when actual file contents haven't changed but one of metadb_display_field_provider implementations requested an update so output of metadb_handle::format_title() etc has changed.
