TFPBinaryXOrOperation class

In unit fpExprPars

Internally used class for binary XOR logical operation

Declaration

pascal

TFPBinaryXOrOperation = class(TFPBooleanOperation)

Inheritance

Description

The TFPBinaryXOrOperation class implements the logical XOR (exclusive OR) operation between two boolean operands. It extends TFPBooleanOperation to provide XOR-specific functionality that evaluates to True when exactly one operand is True.

The XOR operation returns True only when the operands have different boolean values (True XOR False or False XOR True), and returns False when both operands have the same value (True XOR True or False XOR False).

Unlike AND and OR operations, XOR requires evaluation of both operands since both values are needed to determine the result.
