org.elasticsearch.lucene.spatial.Component2DVisitor

All Implemented Interfaces:

TriangleTreeVisitor

public abstract class Component2DVisitor
extends TriangleTreeVisitor.TriangleTreeDecodedVisitor

A TriangleTreeVisitor.TriangleTreeDecodedVisitor implementation for Component2D geometries. It can solve spatial relationships against a serialize triangle tree.

Method Details

matches

public abstract boolean matches()

If the relationship has been honour.

reset

public abstract void reset()

Reset the visitor to the initial state.

pushDecodedX

protected boolean pushDecodedX(double minX)

Description copied from class: TriangleTreeVisitor.TriangleTreeDecodedVisitor

Equivalent to TriangleTreeVisitor.TriangleTreeDecodedVisitor.pushX(int) but coordinates are decoded.

Specified by:

pushDecodedX in class TriangleTreeVisitor.TriangleTreeDecodedVisitor

pushDecodedY

protected boolean pushDecodedY(double minY)

Description copied from class: TriangleTreeVisitor.TriangleTreeDecodedVisitor

Equivalent to TriangleTreeVisitor.TriangleTreeDecodedVisitor.pushY(int) but coordinates are decoded.

Specified by:

pushDecodedY in class TriangleTreeVisitor.TriangleTreeDecodedVisitor

pushDecoded

protected boolean pushDecoded(double maxX,
 double maxY)

Description copied from class: TriangleTreeVisitor.TriangleTreeDecodedVisitor

Equivalent to TriangleTreeVisitor.TriangleTreeDecodedVisitor.push(int, int) but coordinates are decoded.

Specified by:

pushDecoded in class TriangleTreeVisitor.TriangleTreeDecodedVisitor

pushDecoded

protected boolean pushDecoded(double minX,
 double minY,
 double maxX,
 double maxY)

Description copied from class: TriangleTreeVisitor.TriangleTreeDecodedVisitor

Equivalent to TriangleTreeVisitor.TriangleTreeDecodedVisitor.push(int, int, int, int) but coordinates are decoded.

Specified by:

pushDecoded in class TriangleTreeVisitor.TriangleTreeDecodedVisitor

pushDecoded

protected abstract boolean pushDecoded(org.apache.lucene.index.PointValues.Relation relation)

Relation between the query shape and the doc value bounding box. Depending on the query relationship, decide if we should traverse the tree.

Returns:

if true, the visitor keeps traversing the tree, else it stops.

getVisitor

public static Component2DVisitor getVisitor(org.apache.lucene.geo.Component2D component2D,
 org.apache.lucene.document.ShapeField.QueryRelation relation,
 CoordinateEncoder encoder)

Creates a visitor from the provided Component2D and spatial relationship. Visitors are re-usable by calling the reset() method.
