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().
