Example 2 with CalFacadeSubscriptionLoopException

use of org.bedework.calfacade.exc.CalFacadeSubscriptionLoopException in project bw-calendar-engine by Bedework.

the class FilterBuilder method makeColFilter.

/* Create a filter for the supplied collection object.
   *
   * explicitSelection is true if we have a single path and it refers directly
   * to the given collection, e.g. /user/xxx/Inbox
   *
   * This allows us to see the contents of the inbox for example, but not to
   * include it when given paths like /user/xxx
   *
   * pathElement is used to detect loops in the actual path. We fail with an
   * exception if we discover a repeated URI in the list.
