All Implemented Interfaces:

BinaryLogicOpFilter, java.io.Serializable

public class And
extends Filter
implements BinaryLogicOpFilter

The abstract class of <And> elements.

And is a logical operator representing logical operation And. It can be used to combine various Filter elements such as spatial operators, numerical operators, and logical operators, creating more complicated compound expressions.

An And element consists of two or more child Filter elements on which the And operation is performed.
