java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.document.LatLonDocValuesQuery

class LatLonDocValuesQuery
extends Query

Finds all previously indexed geo points that comply the given ShapeField.QueryRelation with the specified array of LatLonGeometry.

The field must be indexed using LatLonDocValuesField added per document.

 LatLonGeometry... geometries)

Method Details

toString

public String toString(String field)

Description copied from class: Query

Prints a query to a string, with field assumed to be the default field and omitted.

Specified by:

toString in class Query

equals

public boolean equals(Object obj)

Description copied from class: Query

Override and implement query instance equivalence properly in a subclass. This is required so that QueryCache works properly.

Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical that other instance. Utility methods are provided for certain repetitive code.

Specified by:

equals in class Query

See Also:

• Query.sameClassAs(Object)
• Query.classHash()

hashCode

public int hashCode()

Description copied from class: Query

Override and implement query hash code properly in a subclass. This is required so that QueryCache works properly.

Specified by:

hashCode in class Query

See Also:

• Query.equals(Object)

visit

public void visit(QueryVisitor visitor)

Description copied from class: Query

Recurse through the query tree, visiting any child queries

Specified by:

visit in class Query

Parameters:

visitor - a QueryVisitor to be called by each query in the tree

createWeight

public Weight createWeight(IndexSearcher searcher,
 ScoreMode scoreMode,
 float boost)
                    throws IOException

Description copied from class: Query

Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.

Overrides:

createWeight in class Query

scoreMode - How the produced scorers will be consumed.

boost - The boost that is propagated by the parent queries.

Throws:

IOException

disjoint

private TwoPhaseIterator disjoint(SortedNumericDocValues values,
 GeoEncodingUtils.Component2DPredicate component2DPredicate)

contains

private TwoPhaseIterator contains(SortedNumericDocValues values,
 LatLonGeometry[] geometries)
