Class SpatialEnvelopeVisitor.GeoPointVisitor

java.lang.Object

org.elasticsearch.geometry.utils.SpatialEnvelopeVisitor.GeoPointVisitor

All Implemented Interfaces:

SpatialEnvelopeVisitor.PointVisitor

Enclosing class:

SpatialEnvelopeVisitor

public static class SpatialEnvelopeVisitor.GeoPointVisitor
extends Object
implements SpatialEnvelopeVisitor.PointVisitor

The geographic point visitor determines the envelope by the minimum and maximum x/y coordinates, while allowing for wrapping the longitude around the dateline. When longitude wrapping is enabled, the visitor will determine the smallest bounding box between the two choices:

• Wrapping around the front of the earth, in which case the result will have minx < maxx
• Wrapping around the back of the earth, crossing the dateline, in which case the result will have minx > maxx
