Detailed Description

The QProtobufBaseSerializer 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 directly.

This class should be used as a base for specific serializers. The handlers property contains all message-specific serializers and should be used while serialization/deserialization. Inherited classes should reimplement scope of virtual methods that used by registered message serialization/deserialization functions.

Member Function Documentation

[pure virtual] bool QProtobufBaseSerializer::deserializeEnum(QtProtobuf::int64 &value, const QMetaEnum &metaEnum) const

This function deserializes an enum value from a wire. metaEnum helps to decode the enum value. Returns true if deserialization was successful, otherwise false.

You should not call this function directly.

See also QProtobufBaseSerializer::serializeEnum().

[pure virtual] bool QProtobufBaseSerializer::deserializeEnumList(QList<QtProtobuf::int64> &value, const QMetaEnum &metaEnum) const

This function deserializes a list of enum value from a wire. metaEnum helps to decode the enum value. Returns true if deserialization was successful, otherwise false.

You should not call this function directly.

See also QProtobufBaseSerializer::serializeEnumList().

[pure virtual] bool QProtobufBaseSerializer::deserializeListObject(QProtobufMessage *message, const QtProtobufPrivate::QProtobufPropertyOrdering &ordering) const

This function deserializes an message from byte stream as part of list property, with the associated message ordering from a wire. Returns true if deserialization was successful, otherwise false.

You should not call this function directly.

See also QProtobufBaseSerializer::serializeListObject().

[pure virtual] bool QProtobufBaseSerializer::deserializeMapPair(QVariant &key, QVariant &value) const

This function deserializes a pair of key and value from a wire. Returns true if deserialization was successful, otherwise false.

You should not call this function directly.

See also QProtobufBaseSerializer::serializeMapPair().

[pure virtual] bool QProtobufBaseSerializer::deserializeObject(QProtobufMessage *message, const QtProtobufPrivate::QProtobufPropertyOrdering &ordering) const

This function deserializes a registered Protobuf message message with defined ordering. message must not be nullptr. Returns true if deserialization was successful, otherwise false.

You should not call this function directly.

See also QProtobufBaseSerializer::serializeObject().

[pure virtual] void QProtobufBaseSerializer::serializeEnum(QtProtobuf::int64 value, const QMetaEnum &metaEnum, const QtProtobufPrivate::QProtobufPropertyOrderingInfo &fieldInfo) const

This function serializes value from enum associated with property fieldInfo. metaEnum helps to encode the enum value.

You should not call this function directly.

See also QProtobufBaseSerializer::deserializeEnum().

[pure virtual] void QProtobufBaseSerializer::serializeEnumList(const QList<QtProtobuf::int64> &value, const QMetaEnum &metaEnum, const QtProtobufPrivate::QProtobufPropertyOrderingInfo &fieldInfo) const

This function serializes a list, value, for enum list associated with property fieldInfo. metaEnum helps to encode the enum value.

You should not call this function directly.

See also QProtobufBaseSerializer::deserializeEnumList().

[pure virtual] void QProtobufBaseSerializer::serializeListObject(const QProtobufMessage *message, const QtProtobufPrivate::QProtobufPropertyOrdering &ordering, const QtProtobufPrivate::QProtobufPropertyOrderingInfo &fieldInfo) const

This function serializes message as part of a list of messages one by one with ordering and fieldInfo.

You should not call this function directly.

See also QProtobufBaseSerializer::deserializeListObject().

[pure virtual] void QProtobufBaseSerializer::serializeMapPair(const QVariant &key, const QVariant &value, const QtProtobufPrivate::QProtobufPropertyOrderingInfo &fieldInfo) const

This function serializes pair of key and value, that belong as a protobuf map record, according to fieldInfo.

You should not call this function directly.

See also QProtobufBaseSerializer::deserializeMapPair().

[pure virtual] void QProtobufBaseSerializer::serializeObject(const QProtobufMessage *message, const QtProtobufPrivate::QProtobufPropertyOrdering &ordering, const QtProtobufPrivate::QProtobufPropertyOrderingInfo &fieldInfo) const

This function serializes a registered Protobuf message message with defined ordering and fieldInfo, that is recognized like an object, into a QByteArray. message must not be nullptr.

You should not call this function directly.

See also QProtobufBaseSerializer::deserializeObject().
