Class FilterBuilder

java.lang.Object
org.bedework.calfacade.filter.FilterBuilder
All Implemented Interfaces:
org.bedework.util.logging.Logged
public class FilterBuilder extends Object implements org.bedework.util.logging.Logged
This class builds a filter expression given a set of paths. Given one or more paths we create a filter to represent each path. Each path pi will produce an associated filter f-pi. What we return is f-p1 | f-p2 | ... | f-pn A path pi could point directly at an unfiltered collection Ci. The filter then becomes simply that collection. Alternatively that collection might have a filter f-ci. The result is Ci & f-ci We can have a chain of filters on aliases with an eventual target of Ci For example A1 -> A2 -> A3 -> Ci where each A is an alias If each A has a filter f-ai the above gives us Ci & f-a1 & f-a2 & f-a3 For folders we or the resulting filter for each sub-path. The end result is a set of filters applied directly to one or more calendar collections. (C1 & f1) | (C2 & f2) | ... (Cn & fn) It is probable that many of the Ci are the same collection so we should gather all the Ci together. In the one calendar model this would result in C1 & (f1 | f2 | ... | fn) What is less likely, though still possible, is a set of common sub-expressions which can be factored out

      public org.bedework.caldav.util.filter.FilterBase buildFilter(String path, boolean applyFilter, boolean explicitSelection)
      Build a filter from the given path. The applyFilter flag only applies to the root of the tree. The filter may already have been processed by the caller.
      Parameters:
      path -
      applyFilter - applies only to root of tree
      Returns:
      FilterBase or null
