All Implemented Interfaces:

public class TLcdOGCBinaryLogicOperator extends TLcdDataObject implements ILcdOGCCondition
This class represents the elements of type <ogc:BinaryLogicOpType>. Namely:
  • <ogc:And>
  • <ogc:Or>
According to the OGC Filter specification, a logical operator can be used to combine one or more conditional expressions. The logical operator AND evaluates to TRUE if all the combined expressions evaluate to TRUE. The operator OR operator evaluates to TRUE if any of the combined expressions evaluate to TRUE.

A TLcdOGCBinaryLogicOperator instance is composed of a logic operation type that must be one of the constants defined in this class and two or more ILcdOGCCondition instances that represents the condition operands.
