Detailed Description

Callback service receiving notifications about metadb contents changes.

Reimplemented from service_base.

virtual void metadb_io_callback::on_changed_sorted	(	const pfc::list_base_const_t< metadb_handle_ptr > &	p_items_sorted,
		bool	p_fromhook
	)			`[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 contents haven't changed but one of display hooks requested an update.
