All Implemented Interfaces:

java.io.Serializable

public class Contains
extends SpatialFilter

The abstract class of <Contains> elements.

Contains is a spatial operator representing the containing operation, i.e., confining result features to ones that contain a specified geometric object. The dimension of the specified geometric object cannot be higher than that of the element.

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