        Invoked before writing of a collection item.
        Parameters:
        index - 0-based index of this item in the collection
        total - total number of items in the collection
        Returns:
        output target that should be used for processing of this collection item. May return this target or an custom sub-target.
      • endCollectionItem

        protected void endCollectionItem​(GeometryUtils.Target target,
                                         int type,
