Class AbstractVisitingPrefixTreeFilter

Traverses a SpatialPrefixTree indexed field, using the template & visitor design patterns for subclasses to guide the traversal and collect matching documents.

Subclasses implement Lucene.Net.Search.Filter.GetDocIdSet(Lucene.Net.Index.AtomicReaderContext, Lucene.Net.Util.IBits) by instantiating a custom AbstractVisitingPrefixTreeFilter.VisitorTemplate subclass (i.e. an anonymous inner class) and implement the required methods.
