Learn to use PROTOBUF to create Java filesWindows:Step one: Two files: Proto.exe, Protobuf-java-2.4.1.jarStep two: Establish a project createprotobuf, create a proto file below, to store "proto" fileStep three: Put the Proto,exe under the project,Step four: Create a Msg.proto file:1Option Java_package ="Com.protobuftest.protobuf"; 2Option Java_outer_classname ="Personprobuf"; 3 4 Message Person5 { 6Require

The serialized data of Google protobuf messages has no type information. In general, network applications require serialization and sending it to the peer end, restoring the type, deserializing it, and then sending it to the corresponding message processing function. The following code implements the automatic dispatch mechanism. To add a protobuf message, you only need to add a line of declared code and c

Use Protobuf 3.4 and pythonprotobuf in Python 2.6In the development field, the use of protocols is a frequent issue. It is necessary to use the Protocol whenever communication is needed. For example, communication between a client and a server, such as communication between an embedded system and a host computer,For example, data communication between different processes is required. However, there are also many methods to define the protocol. The mos

In order to make game development more convenient and convenient, I continued to try protobuf under lua. The socket uses the websocket integrated with cocos2dx. Let's talk about the environment: cocos2d-x-2.2.1 + protobuf 2.5.0 + protoc-gen-lua + Python 2.7.5 1. run the following command [plain] python setup in sequence under the protobuf directory. py build pyth

A message that, when serialized, first even if the message all filed serialization needs to occupy the length of bytes, the calculation of this length is very simple, because protobuf in each type of filed occupies a known number of bytes (except bytes, string), You just need to accumulate. This length is serializedsize,32 as an integer, and in some of the serialization methods of PROTOBUF it is possible to

There are two main ways of integrating LUA Protobuf1. Protobuf-gen-lua programmeHttps://github.com/sean-lin/protoc-gen-lua Reference instructions to integrateThe solution is to export the proto file to a LUA file, which is a little cumbersome to use, not to create the LUA table directly, but to generate the binary with a table in the format specified in the LUA PB file, and the binary data returned by the server is also deserialized to generate LUA Th

and result_per_page ), one string type (query). Of course, you can also specify other composition types for the field, including enumerations (enumerations) or other message types. 2. Assigning identification numbers As in the file format above, each field has a unique numeric identifier in the message definition. These identifiers are used to identify each field in the binary format of the message and cannot be changed once it is started. Note: the identification number within [1,15] occ

Let's not talk nonsense.1. Install: Download down, find a path to put it. Https://github.com/golang/protobufThis is not enough because you will find that you cannot use Protoc to download the C + + version to Protobuf website, see readme,./configure make make install.2. Use: Write a proto file, the beginning of the file to indicate PackageName and then runProtoc--go_out=src/proto Proto/*. ProtoWhen used, the import corresponds to the proto PackageNa

Looking at Google protocol buffers documents for the last two days, protobuf is very good and solves the problem of different versions of the messages that have been encountered, which is very helpful in developing projects.Recently learning Erlang, the official only Java, C + +, Python protobuf implementation, the third party has two Erlang implementations:Http://github.com/ngerakines/erlang_protobuffs/tre
