All Implemented Interfaces:

java.io.Serializable

public class Equals
extends SpatialFilter

The abstract class of <Equals> elements.

Equals is a spatial operator, representing the equals operation, i.e., confining result features to ones that coincide with a specified geometric object spatially.

A Equals element consists of the name of the field storing geometric object, and the target geometric object participating in the operation.
