public class TLcdOGCBinaryOperator
extends TLcdDataObject
implements ILcdOGCExpression

This class represents the elements of type <ogc:BinaryOperatorType>. Namely:

• <ogc:Add>
• <ogc:Mul>
• <ogc:Sub>
• <ogc:Div>

According to the OGC Filter specification, these elements defined are used to encode the fundamental arithmetic operations of addition, subtraction, multiplication and division. Arithmetic operators are binary operators meaning that they accept two arguments and evaluate to a single result.

A TLcdOGCBinaryOperator instance is composed of an arithmetic operation type that must be one of the constants defined in this class, and two operands that can be any instances of ILcdOGCExpression.

Note that the OGC Filter 2.0 standard no longer includes the binary operators. You will get an IllegalArgumentException when you use this operator in OGC Filter 2.0 XML (for example WFS 2.0).
