Preface: Because OBJECT-C does not support multiple inheritance, it is often replaced with protocol (protocol). The Protocol (protocol) can only define a common set of interfaces, but cannot provide a specific implementation method. That is, it only tells you what to do, but specifically how to do it, it does not care.
increase can make your code lighter and faster, and strongly typed mappings can check for Errors.Don't think You're done Here. There is also a faster library, but now only supports proto2, called pyrobuf library. based on the CPython implementation, according to the author, he is 2-4 times faster than C + + backend for Python. This because I installed a half-day not installed, it seems that the configuration of the CPython library a little bit of a problem, if you have faster requirements for

After a rough understanding of IP address relays and IP addresses, let's look at the specific details and design philosophy of the IP protocol. Comparison between IPv4 and IPv6 Headers We have already introduced in IP address relay that an IP packet is dividedHeader(Header) andData(Payload/data. The header is the additional infor

It uses Secure Sockets Layer (SSL) for information exchange, which simply means that it is a secure vers
NetBIOS protocol (NetWork Basic Input/Output System). This protocol is developed by IBM and is mainly used for the small LAN of dozens of computers. The NetBIOS protocol is an Application Programming Interface API that can be used by a program on the LAN. It provides a unified command set for the program to request low-level services, it serves to provide network

The protocol in iOS is the declaration of a method, stating that no implementation is required, and that the part of the implementation is done by the compliance party.Look at a small example of a protocol: this example is to give two protocols, and then create two types of people to abide by the agreement.Rogue Protocol (ROGUEDELEGATE.H) #import/** Rogue
Recently in the "HTTP diagram" This book, the book mentions the domestic translation of the name of the HTTP protocol, and give some friends to discuss the original link, I looked at a bit of interesting, and I also think that translation for understanding the agreement itself is very important, the collation of some ideas.The full name of HTTP is Hypertext Transfer Protocol, and the main concern is how Tra
Today's Web program development technology is really a contention, ASP, PHP, Jsp,perl, AJAX and so on. Regardless of how web technologies evolve in the future, it is important to understand the basic protocols for communicating between web programs, because it allows us to understand the internal work of Web applications. This article will be a detailed example of the HTTP protocol to explain, more content, I hope you have patience to see. We also hop

"OSI layer Seven Protocol" Application Layer An application that communicates with other computers, which is the communication service of the corresponding application. For example, a word processor without a communication function would not be able to execute the code of communication, and the programmer working on the word processing did not care about the 7th layer of the OSI. However, if you add an option to transfer files, the programmer of the
