AbstractVisitingPrefixTreeQuery (Lucene 10.5.1 spatial-extras API)
Description: declaration: package: org.apache.lucene.spatial.prefix, class: AbstractVisitingPrefixTreeQuery

Package org.apache.lucene.spatial.prefix

# Class AbstractVisitingPrefixTreeQuery

java.lang.Object
org.apache.lucene.search.Query
org.apache.lucene.spatial.prefix.AbstractPrefixTreeQuery
org.apache.lucene.spatial.prefix.AbstractVisitingPrefixTreeQuery

Direct Known Subclasses:
  `IntersectsPrefixTreeQuery`, `WithinPrefixTreeQuery`

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.
