Method Detail

visit

public void visit(QueryVisitor visitor)

Description copied from class: Query

Recurse through the query tree, visiting any child queries

Overrides:

visit in class Query

Parameters:

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

getIntersectVisitor

private PointValues.IntersectVisitor getIntersectVisitor(DocIdSetBuilder result,
                                                         Component2D tree,
                                                         GeoEncodingUtils.PolygonPredicate polygonPredicate,
                                                         byte[] minLat,
                                                         byte[] maxLat,
                                                         byte[] minLon,
                                                         byte[] maxLon)

createWeight

public Weight createWeight(IndexSearcher searcher,
                           ScoreMode scoreMode,
                           float boost)
                    throws java.io.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:

java.io.IOException

getField

public java.lang.String getField()

Returns the query field

getPolygons

public Polygon[] getPolygons()

Returns a copy of the internal polygon array

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)

equals

public boolean equals(java.lang.Object other)

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()

equalsTo

private boolean equalsTo(LatLonPointInPolygonQuery other)

toString

public java.lang.String toString(java.lang.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
