public abstract class AbstractVisitingPrefixTreeQuery
extends AbstractPrefixTreeQuery

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

Subclasses implement AbstractPrefixTreeQuery.getDocIdSet(org.apache.lucene.index.LeafReaderContext) by instantiating a custom AbstractVisitingPrefixTreeQuery.VisitorTemplate subclass (i.e. an anonymous inner class) and implement the required methods.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
