protobuf c tutorial

To learn about Protobuf's protocol generation, you'll need to download its code from the Web and download it from this SVN address: Http://protobuf.googlecode.com/svn/trunk After the download is complete, you can go to the Protobuf\vsprojects directory to find the VC2008 project file, and then open the project for conversion, this is no problem. However, there are two problems in the compilation process, the first of which is as follows: 1>------Bu

Protobuf and iosprotobuf for iOS Network Communication Abstract: objects must be serialized before communication between different platforms. On the iOS platform, we often use 'nskeyedarchiver 'for archiving. Of course, we can also process data in JSON or XML format. 'Nskeyedarchiver 'can only be used on iOS/Mac platforms. Therefore, the binary data archived by NSKeyedArchiver is not suitable for different platforms. JSON and XML are widely used becau

E_clkurl, Clkurl)After viewing the source code, it is found that the second parameter is reflected when the value of the extension field is evaluated to obtain the type, to determine whether the type of the third parameter and the second match,Func setextension (pb Message, extension *extensiondesc, value inte

to link libprotobuf-lite, not libprotobuf. In Java, you only need to include Protobuf-java-2.4.1-lite.jar, not Protobuf-java-2.4.1.jar.Speed is compared to lite_runtime at the debug level, such as MSG. Serializetostring (STR) uses the reflection mechanism to print detailed fields and field values in Speed mode, but lite_runtime only prints strings that consist of field values;Therefore: You can use the spe

In order to adapt directly to the class object serialization attempt to Msgpack, BinaryFormatter, Jsonfx, Newtonsoft.json/bson, flatbuffers these sequence library to do iOS, Android, WP under the sequence of experiments , not the whole platform through, mainly iOS and WP do not, including a few are in the WP app can, but in unity WP not because of Unity's. NETFramework only support to. NET 3.5 subset, some advanced syntax in the serialization library is not supported, So around a circle can only

An in-depth explanation of PROTOBUF The protobuf of my understanding, summed up as the following points: 1. PB is a coding method. This is because some people think it is a protocol, it is chivalrous, PB is essentially the same as JSON, XML, is a way of encoding, with PB-encoded streams can be nested in any existing protocol, as part of the content, such as can be placed in the contents of the HTTP area, o

Base 128 varintsProtobuf uses a encoding method called "base 128 varints". It uses one or more bytes to serialize an integer. The smaller the numbe

Protocol Buffer (PB) is a format for Google's data interchange, which is independent of the language and platform-independent. Google offers implementations in three languages: Java, C + +, and Python, each with a compiler and library file for the appropriate language. Because it is a binary format, it is much faster than using XML for data exchange. It can be used in data communication between distributed applications or in heterogeneous environments. As a good efficiency and compatibility of t

Encoding Decoding once. It is transparently transmitted in other cases. Zoned processing process Zoned receives total_len + gzmessage_len + gzmessage + csmessage. Total_len is used for TCP stream, and gzmessage_len is used for zoned to parse gzmessage. Zoned first parses the gzmessage and sends the csmessage to the logic layer. One advantage of the above process is that there is no large amount of unneeded protobuf message parsing. Head inf

Abstract when communicating on different platforms, the object needs to be serialized first. We use ' nskeyedarchiver ' for archiving on the iOS platform, and of course we can use data processing in JSON or XML format. ' Nskeyedarchiver ' is only available on the Ios/mac platform, so its archived binary data is not suitable for use between different platforms. JSON and XML, although easy to maintain, easy to read and widely used, but the use of data efficiency is not high. Google proposed Protoc

To avoid this warning, please use the java_outer_classname option to specify a different outer class name for the. Proto F IleReason:1.Java the file name must be the same as the class name;2.

Today, while executing a PROTOBUF program, you are prompted for the error while loading shared Libraries:libprotobuf.so.8:cannot open Shared object file:no such file or directory error. Google a bit, because the file can not find Lib. Solution: In general, when we execute some external programs under Linux, we may be prompted not to find a shared library error, such as: Tmux:error while loading shared libraries:libevent-1.4.so.2:cannot open Shared ob
