QProtobufMessagePointer QProtobufMessage::constructByName(const QString &messageType)
Constructs QProtobufMessage using messageType. Returns a pointer to the constructed QProtobufMessage.
This function attempts to create a message whose type matches messageType. If messageType is unknown, the function returns nullptr
. If the message is not found in the registry, the function returns nullptr
. Ownership of the constructed message is given to the function caller.
QVariant QProtobufMessage::property(QAnyStringView propertyName) const
Get the value of the property propertyName.
If the propertyName isn't known then the returned QVariant is invalid.
See also setProperty().
bool QProtobufMessage::setProperty(QAnyStringView propertyName, const QVariant &value)
Set the property propertyName to the value stored in value.
If the propertyName isn't a part of the known fields then the value will not be written and the function returns false
.
Returns false
if it failed to store the value on the property. Otherwise true
.
See also property().
[since 6.6]
bool QProtobufMessage::setProperty(QAnyStringView propertyName, QVariant &&value)
This is an overloaded function.
This function was introduced in Qt 6.6.
[since 6.7]
QList<QByteArray> QProtobufMessage::unknownFieldData(qint32 field) const
Returns the unknown field values sorted as they were received from the wire.
This function was introduced in Qt 6.7.
[since 6.7]
QList<qint32> QProtobufMessage::unknownFieldNumbers() const
Returns the field numbers that were not known to QtProtobuf during deserialization.
This function was introduced in Qt 6.7.
