[static] QProtobufMessagePointer QProtobufMessage:: constructByName (const QString & messageType )

構造 QProtobufMessage 使用 messageType . Returns a pointer to the constructed QProtobufMessage .

This function attempts to create a message with a type that matches messageType 。若 messageType is unknown, the function returns nullptr . If the message is not found in the registry, the function returns nullptr . The function caller is given ownership of the constructed message.

[since 6.8] bool QProtobufMessage:: deserialize ( QAbstractProtobufSerializer * serializer , QByteArrayView data )

Deserializes this protobuf message from a QByteArray data 使用 serializer 。返迴 true if deserialization was successful, otherwise false .

該函數在 Qt 6.8 引入。

另請參閱 serialize ().

QVariant QProtobufMessage:: property ( QAnyStringView propertyName ) const

Get the value of the property propertyName .

若 propertyName isn't known then the returned QVariant 無效。

另請參閱 setProperty ().

[since 6.8] const QtProtobufPrivate::QProtobufPropertyOrdering *QProtobufMessage:: propertyOrdering () const

Returns the pointer to the property ordering of the derived protobuf message.

該函數在 Qt 6.8 引入。

[since 6.8] QByteArray QProtobufMessage:: serialize ( QAbstractProtobufSerializer * serializer ) const

Serializes this protobuf message into a QByteArray 使用 serializer .

該函數在 Qt 6.8 引入。

另請參閱 deserialize ().

bool QProtobufMessage:: setProperty ( QAnyStringView propertyName , const QVariant & value )

Set the property propertyName to the value stored in value .

若 propertyName isn't a known fields, then the value is ignored, and the function returns false .

返迴 false if it fails to store the value on the property. Otherwise true .

另請參閱 property ().

[since 6.6] bool QProtobufMessage:: setProperty ( QAnyStringView propertyName , QVariant && value )

這是重載函數。

該函數在 Qt 6.6 引入。

[since 6.7] QList < QByteArray > QProtobufMessage:: unknownFieldData ( qint32 field ) const

Returns the unknown field values sorted as they were received from the wire.

該函數在 Qt 6.7 引入。

[since 6.7] QList < qint32 > QProtobufMessage:: unknownFieldNumbers () const

Returns the field numbers that were not known to QtProtobuf during deserialization.

該函數在 Qt 6.7 引入。

[alias] QProtobufMessagePointer

Synonym for std::unique_ptr< QProtobufMessage , QProtobufMessageDeleter >. Use this to manage the lifetime of dynamically allocated QProtobufMessages, such as those created by calling QProtobufMessage::constructByName .
