Class StDistance.DistanceCalculator

java.lang.Object

org.elasticsearch.xpack.esql.expression.function.scalar.spatial.BinarySpatialFunction.BinarySpatialComparator<Double>

org.elasticsearch.xpack.esql.expression.function.scalar.spatial.StDistance.DistanceCalculator

Direct Known Subclasses:

StDistance.CartesianDistanceCalculator, StDistance.GeoDistanceCalculator

Enclosing class:

StDistance

public abstract static class StDistance.DistanceCalculator
extends BinarySpatialFunction.BinarySpatialComparator<Double>

This class is a CRS specific interface for generalizing distance calculations for the various possible ways that the geometries can be provided, from source, from evals, from literals and from doc values.
