成员函数文档编制

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

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

This function attempts to create a message whose type matches messageType 。若 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 .

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

另请参阅 setProperty ().

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

Set the property propertyName to the value stored in value .

若 propertyName isn't a part of the known fields then the value will not be written and the function returns false .

返回 false if it failed to store the value on the property. Otherwise true .

另请参阅 property ().

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

这是重载函数。

该函数在 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.

该函数在 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.

该函数在 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 .
