Example 8 with CurrentAccess

Example 9 with CurrentAccess

use of org.bedework.access.Acl.CurrentAccess in project bw-calendar-engine by Bedework.

the class CoreEvents method doRecurrence.

/* Retrieves the overides for a recurring event and if required,
   * retrieves the instances.
   *
   * The overrides we retrieve are optionally limited by date.
   *
   * The CalDAV spec requires that we retrieve all overrides which fall within
   * the given date range AND all instances in that date range including
   * overriden instances that WOULD have fallen in that range had they not been
   * overriden.
   *
   * Thus we need to search both overrides and instances - unless no date range
   * is given in which case all overrides will appear along with the instances.
   *
   * If the calendars parameter is non-null, as it usually will be for a call
   * from getEvents, we limit the result to instances that appear within that
   * set of calendars. This handles the case of an overriden instance moved to a
   * different calendar, for example the trash.
