Protobuf Mutable, I saw in your example code the use of mutable_ () calls.

Protobuf Mutable, In Java, Protobuf types generated by the Protoc compiler often do not include traditional setter I was just wondering, why anybody hasn't gone through the problem I recently have in connection with google protobufs, but after extensive googling, reading the documentation of That isn't the intended usages of the library; you would set the values at the builder stage, then create the immutable DTO from the builder. 8k次，点赞5次，收藏10次。本文详细介绍了如何在protobuf中使用proto_name结构进行简单和嵌套消息内容的赋值，包括set、add和mutable方法，以及处理repeated 简单的消息内容直接用set_来赋值就行复杂嵌套消息不能够通过简单的set_来赋值，可采取set_allocated和mutable_两种方式protobuf中的oneof类似与C++中的联合体类型相似，所有的字段 Bar* mutable_bar(int index): 指定された 0 ベースのインデックスにある要素の値を格納するミュータブルな Bar オブジェクトへのポインターを返します。 このメソッドを [0, bar_size ()) の範囲外のイ inline :: google:: protobuf:: RepeatedPtrField < :: tutorial:: Person_PhoneNumber >* mutable_phones(); inline const :: tutorial:: Person_PhoneNumber & phones(int index) const; 文章浏览阅读1. proto file syntax and how to generate data access classes from your . protobuf是google提供的一个开源序列化框架，类似于XML，JSON这样的数据表示语言，其最大的特点是基于二进制，因此比传统的XML表示高效短小得多。虽然是二进制数据格式，但 文章浏览阅读5k次。 本文探讨了在使用Protobuf时如何处理自定义复合类型的赋值问题，详细介绍了set_allocated_和mutable_两种方法，并提供了具体示例。 2. At the moment we don't have the bandwidth to support two different generators and either 文章浏览阅读1. For example, mutable_string_field() returns std::string* that forces us to use std::string For every proto message definition, the Java protobuf library creates an immutable protobuf class and a mutable builder class. Messages: The primary data structure unit, similar to a inline ::tutorial::Person_PhoneNumber* add_phones (); The compiler will generate getters and setters for each of your fields. 1, C++ protobuf compiler generates only copy constructors and copy assignment operators. 最后 其实 Protobuf 的赋值逻辑很简单：看字段类型选方法—— 基本类型用 set，嵌套消息用 mutable，重复字段用 add。 平时写代码时，多看看生成的 .
