Member Function Documentation
QOpcUaDataValue::QOpcUaDataValue()
Constructs an invalid data value.
QOpcUaDataValue::QOpcUaDataValue(const QOpcUaDataValue &other)
Constructs a data value from other.
QOpcUaDataValue::~QOpcUaDataValue()
Destroys the data value.
QDateTime QOpcUaDataValue::serverTimestamp() const
Returns the server timestamp for value().
See also setServerTimestamp().
void QOpcUaDataValue::setServerTimestamp(const QDateTime &serverTimestamp)
Sets the server timestamp to serverTimestamp.
See also serverTimestamp().
void QOpcUaDataValue::setSourceTimestamp(const QDateTime &sourceTimestamp)
Sets the source timestamp to sourceTimestamp.
See also sourceTimestamp().
void QOpcUaDataValue::setStatusCode(QOpcUa::UaStatusCode statusCode)
Sets the status code to statusCode.
See also statusCode().
void QOpcUaDataValue::setValue(const QVariant &value)
Sets the value to value.
See also value().
QDateTime QOpcUaDataValue::sourceTimestamp() const
Returns the source timestamp for value().
See also setSourceTimestamp().
QOpcUa::UaStatusCode QOpcUaDataValue::statusCode() const
Returns the status code for this data value. If the status code is not Good, the value and the timestamps are invalid.
See also setStatusCode().
void QOpcUaDataValue::swap(QOpcUaDataValue &other)
Swaps this data value instance with other. This function is very fast and never fails.
QVariant QOpcUaDataValue::value() const
Returns the value.
