com.supermap.services.ogc.filter.PropertyIsEqualTo

All Implemented Interfaces:

java.io.Serializable

public class PropertyIsEqualTo
extends AbstractBinaryExpression

The abstract class of <PropertyIsEqualTo> elements.

It's a binary comparison operation confining that the values of two expressions are the same.

A PropertyIsEqualTo element consists of two <expression> child elements.

Where, the <expression> element is a composite expression of Filter elements. It is an abstract element in OGC and does not actually exist. It represents an expression with a combination of some Filter elements. The Filter elements that can be combined in a <expression> element include: <Add>, <Sub>, <Mul>, <Div>, <PropertyName>, <Literal> , and <Function>.
