QOpcUaLiteralOperand::QOpcUaLiteralOperand()

Default constructs a literal operand with no parameters set.

QOpcUaLiteralOperand::QOpcUaLiteralOperand(const QVariant &value, QOpcUa::Types type = QOpcUa::Types::Undefined)

Constructs a literal operand of value value and type type.

QOpcUaLiteralOperand::QOpcUaLiteralOperand(const QOpcUaLiteralOperand &rhs)

Constructs a literal operand from rhs.

void QOpcUaLiteralOperand::setType(QOpcUa::Types type)

Sets the type of the value of the literal operand to type.

See also type().

void QOpcUaLiteralOperand::setValue(const QVariant &value)

Sets the value of the literal operand to value.

See also value().

QOpcUa::Types QOpcUaLiteralOperand::type() const

Returns the type of the value of the literal operand.

See also setType().

QVariant QOpcUaLiteralOperand::value() const

Returns the value of the literal operand.

See also setValue().

QVariant QOpcUaLiteralOperand::operator QVariant() const

Converts this literal operand to QVariant.

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

Sets the values from rhs in this QOpcUaLiteralOperand.
