protobuffer语法汇总-c++

拿一个pb为样例

syntax = "proto2";

package tutorial;

message Person {
  required string name = 1;
  required int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }

  repeated PhoneNumber phones = 4;
}

message AddressBook {
  repeated Person people = 1;
}

API

 // required name
  inline bool has_name() const;
  inline void clear_name();
  inline const ::std::string& name() const;
  inline void set_name(const ::std::string& value);
  inline void set_name(const char* value);
  inline ::std::string* mutable_name();

  // required id
  inline bool has_id() const;
  inline void clear_id();
  inline int32_t id() const;
  inline void set_id(int32_t value);

  // optional email
  inline bool has_email() const;
  inline void clear_email();
  inline const ::std::string& email() const;
  inline void set_email(const ::std::string& value);
  inline void set_email(const char* value);
  inline ::std::string* mutable_email();

  // repeated phones
  inline int phones_size() const;
  inline void clear_phones();
  inline const ::google::protobuf::RepeatedPtrField< ::tutorial::Person_PhoneNumber >& phones() const;
  inline ::google::protobuf::RepeatedPtrField< ::tutorial::Person_PhoneNumber >* mutable_phones();
  inline const ::tutorial::Person_PhoneNumber& phones(int index) const;
  inline ::tutorial::Person_PhoneNumber* mutable_phones(int index);
  inline ::tutorial::Person_PhoneNumber* add_phones();
