详细描述

The QProtobufSerializer class registers serializers/deserializers for classes implementing a protobuf message, inheriting QProtobufMessage . These classes are generated automatically, based on a .proto file, using the CMake function qt_add_protobuf or by running qtprotobufgen 直接。

QProtobufSerializer:: QProtobufSerializer ()

Constructs a new serializer instance.

`[override virtual noexcept]` QProtobufSerializer:: ~QProtobufSerializer ()

Destroys the serializer instance.

`[override virtual]` QAbstractProtobufSerializer::Error QProtobufSerializer:: lastError () const

重实现： QAbstractProtobufSerializer::lastError () const.

Returns the last deserialization error for the serializer instance.

另请参阅 lastErrorString ().

`[override virtual]` QString QProtobufSerializer:: lastErrorString () const

重实现： QAbstractProtobufSerializer::lastErrorString () const.

Returns the last deserialization error string for the serializer instance.

另请参阅 lastError ().

`[since 6.7]` void QProtobufSerializer:: shouldPreserveUnknownFields ( bool preserveUnknownFields )

Controls whether the unknown fields received from the wire should be stored in the resulting message or if it should be omitted, based on preserveUnknownFields .

该函数在 Qt 6.7 引入。
