- * calendar-query it is possible for a client to request a specific set of
- * object, based on contents of iCalendar properties, date-ranges and
- * iCalendar component types (VTODO, VEVENT).
- *
- * This method should just return a list of (relative) urls that match this
- * query.
- *
- * The list of filters are specified as an array. The exact array is
- * documented by Sabre\CalDAV\CalendarQueryParser.
- *
- * Note that it is extremely likely that getCalendarObject for every path
- * returned from this method will be called almost immediately after. You
- * may want to anticipate this to speed up these requests.
- *
- * This method provides a default implementation, which parses *all* the
- * iCalendar objects in the specified calendar.
- *
- * This default may well be good enough for personal use, and calendars
- * that aren't very large. But if you anticipate high usage, big calendars
- * or high loads, you are strongly advised to optimize certain paths.
- *
- * The best way to do so is override this method and to optimize
- * specifically for 'common filters'.
- *
- * Requests that are extremely common are:
- * * requests for just VEVENTS
- * * requests for just VTODO
- * * requests with a time-range-filter on either VEVENT or VTODO.
- *
- * ..and combinations of these requests. It may not be worth it to try to
- * handle every possible situation and just rely on the (relatively
- * easy to use) CalendarQueryValidator to handle the rest.
- *
- * Note that especially time-range-filters may be difficult to parse. A
- * time-range filter specified on a VEVENT must for instance also handle
- * recurrence rules correctly.
- * A good example of how to interprete all these filters can also simply
- * be found in Sabre\CalDAV\CalendarQueryFilter. This class is as correct
- * as possible, so it gives you a good idea on what type of stuff you need
- * to think of.
