enum class QtProtobuf:: WireTypes

The WireTypes enumeration reflects protobuf default wiretypes.

The following table shows the values in the enumeration and their corresponding types:

常量	值	描述
QtProtobuf::WireTypes::Unknown	-1	Invalid wire type
QtProtobuf::WireTypes::Varint	0	int32, int64, uint32, uint64, sint32, sint64, bool, enum
QtProtobuf::WireTypes::Fixed64	1	fixed64, sfixed64, double
QtProtobuf::WireTypes::LengthDelimited	2	string, bytes, embedded messages, packed repeated fields
QtProtobuf::WireTypes::StartGroup	3	groups. Deprecated in proto syntax 3. Not supported by Qt Protobuf.
QtProtobuf::WireTypes::EndGroup	4	groups. Deprecated in proto syntax 3. Not supported by Qt Protobuf.
QtProtobuf::WireTypes::Fixed32	5	fixed32, sfixed32, float

函数文档编制

void QtProtobuf:: qRegisterProtobufQtCoreTypes ()

Registers serializers for the Qt::ProtobufQtCoreTypes library.

void QtProtobuf:: qRegisterProtobufQtGuiTypes ()

Registers serializers for the Qt::ProtobufQtGuiTypes library.

void qRegisterProtobufTypes ()

Calling this function registers all, currently known, protobuf types with the serializer registry.

注意： You should not have to call this function manually, as it is called automatically upon attempting serialization or deserialization of a protobuf message.

template <typename T> bool QtProtobuf:: repeatedValueCompare (const QList < T > & a , const QList < T > & b )

Compares two repeated fields (essentially a list) to each other. Returns true if a 等于 b , false 否则。

These functions are used in the generated code to implement operator== .

template <typename K, typename V> bool QtProtobuf:: repeatedValueCompare (const QHash < K , V > & a , const QHash < K , V > & b )

Compares two map fields to each other. Returns true if a 等于 b , false 否则。

These functions are used in the generated code to implement operator== .
