成员函数文档

QOpcUaComplexNumber::QOpcUaComplexNumber()

默认构造一个不带参数的复数。

QOpcUaComplexNumber::QOpcUaComplexNumber(float real, float imaginary)

构造一个复数,其实部real ,虚部imaginary

float QOpcUaComplexNumber::imaginary() const

返回复数的虚部。

另请参见 setImaginary().

float QOpcUaComplexNumber::real() const

返回复数的实部。

另请参见 setReal().

void QOpcUaComplexNumber::setImaginary(float imaginary)

将复数的虚部设置为imaginary

另请参见 imaginary() 。

void QOpcUaComplexNumber::setReal(float real)

将复数的实部设置为real

另请参见 real() 。

QVariant QOpcUaComplexNumber::operator QVariant() const

将此复数转换为QVariant

QOpcUaComplexNumber &QOpcUaComplexNumber::operator=(const QOpcUaComplexNumber &rhs)

在此复数中设置rhs 的值。

bool QOpcUaComplexNumber::operator==(const QOpcUaComplexNumber &rhs) const

如果该复数的值与rhs 相同,则返回true
