Google的Protobuf的使用方式(序列化和反序列化工具编解码)

1 message Person {
2   required string name = 1; -- 1，2,3是表示参数的顺序而不是默认值
3   required int32 id = 2;
4   optional string email = 3;
5 }

1 Person john = Person.newBuilder()
2     .setId(1234)
3     .setName("John Doe")
4     .setEmail("jdoe@example.com")
5     .build();
6 output = new FileOutputStream(args[0]);
7 john.writeTo(output);

//C++语言解码
Person john = Person.newBuilder()
    .setId(1234)
    .setName("John Doe")
    .setEmail("jdoe@example.com")
    .build();
output = new FileOutputStream(args[0]);
john.writeTo(output);
