Class Not

java.lang.Object

com.supermap.services.ogc.filter.Filter

com.supermap.services.ogc.filter.Not

All Implemented Interfaces:

BinaryLogicOpFilter, java.io.Serializable

public class Not
extends Filter
implements BinaryLogicOpFilter

A <Not> element.

Not is a logical operator representing logical operation Not. It can be used to combine various Filter elements such as spatial operators, numerical operators, and logical operators, creating more complicated compound expressions.

A Not element consists of one child Filter element. A Not operation is performed on the result of this Filter element.
