@XmlElement(value="DistanceBufferType")
public interface DistanceBufferOperator
extends BinarySpatialOperator

Abstract superclass for spatial operators that check that one shape satisfies some relation to a buffer around another shape. This could be used to find, for example, all the geometries that come within 10 meters of a river.

Since:

GeoAPI 2.0

Version:

Implementation specification 1.0

Method Summary

double	getDistance() Returns the buffer distance around the geometry that will be used when comparing features' geometries.
String	getDistanceUnits() Gets the units of measure that can be used to interpret the distance value held by this object.

Method Detail

getDistance

@XmlElement(value="Distance")
double getDistance()

Returns the buffer distance around the geometry that will be used when comparing features' geometries.

getDistanceUnits

String getDistanceUnits()

Gets the units of measure that can be used to interpret the distance value held by this object. An implementation may throw an exception if these units differ from the units of the coordinate system of its geometry or the feature's geometry.
