/**
|
|
* Performs a calendar-query on the contents of this calendar.
|
|
*
|
|
* The calendar-query is defined in RFC4791 : CalDAV. Using the
|
|
* 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 adviced 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.
