abstract class testParent{public function abc(){//body of your funciton}}class testChild extends testParent{public function xyz(){//body of your function}}$a = new testChild();
TestChild inherits the abstract class testParent through the keyword extends, and then we can generate a testChild object. Implement Abstract Method
Similar to pure virtual functions in C ++, Abstract methods can only be declared in Abstract classes, but must be defined in subclasses.

In the development process of iOS, often encounter a variety of network access issues, before the lack of capture tools, a lot of network problems to solve the pain. Now that's finally good, this article provides two ways to do network capture:1. Network sharing + Visual Grab Kit
Basic principle
The principle is simple, the iOS device shares the wireless network card which connects the Mac computer through the proxy way, uses the grab Bag tool to grab the bag, then carries on the a

Question: The boss told the secretary to go to Shanghai on business for 10 days; The boss told the Secretary to invite 8 people to dinner. How to design?Answer:1. According to the thinking of the object of the face, there should be a boss class, and secretary Secretary class, in addition, there must be Hotel class hotel, airport airports, hotel class restaurant, driver class chauffeur.2. Boss object is only to talk with the Secretary and not personall
1. The story of Little CHere's a story about the planet of the X-Galaxy Meow and Doggy's two enemies. First, focus the lens on the Meow star, which is where the protagonist comes in. (The story is purely fictitious, if there is a similarity, purely coincidental)In 9035, the doggy elite fleet gathered near the Meow star in an attempt to win the Mew star in a swoop. Most of the cats have been transferred to anti-aircraft fortifications. The King of Meow has ordered the strongest battle to be fough

Let's take the Beijing Metro as an example. IfAirportGoChaoyangmenThen you can take the Terminal 2->Sanyuan Bridge->Dongzhimen->Chaoyangmen. Terminal 2 and chaoyangmen are the departure and destination hosts respectively. The Sanyuan bridge and Dongzhimen are two routers in the middle. IfSanyuan Bridge->DongzhimenBecause the service is out of service, we need to change the routing table of Sanyuan bridge to instruct the passengers (IP packets) heading to

IOS network packet capture method
During iOS development, various network access problems often occur. In the past, packet capture tools were not used, and many network problems were solved. Now, we have finished. This article provides two methods for packet capture:
1. Network Sharing + visual packet capture tools
Basic Principles
The principle is relatively simple. iOS devices share the wireless network card that connects

intermediary mode uses an intermediary object to control a series of object interactions. You can implement loose coupling between objects through intermediaries, rather than directly interacting with each other. The control tower at the airport demonstrates this mode. The plane that lands or departs communicates directly with the tower, rather than directly with each other. It is up to the tower to decide who can take off or land. Note that the towe
hung up the phone number at the airport's inquiry room. The answer I got made me put down my mind. The plane to Shanghai took off on time at noon.My family is very close to the airport and it takes only 20 minutes to get to the airport for rent. So my mother and I decided to leave at and arrive at the airport at, because the plane usually goes through the check-
There are two laptops, One Mac and the other Windows 7 at home. Now we need to allow both computers to access each other's files, so we plan to create a point-to-point Wireless LAN.

First, enable the airport, that is, enable the wireless connection of the apple notebook. Open "system preference settings", click "network", and select "Airport" in the left-side

Implement abstract method
Like pure virtual functions in C + +, we can only declare abstract method in an abstract class, but only and must define it in a subclass.
In fact, this statement is not absolute, but for the convenience of memory, most of the textbooks said so, let us review the effective C + + in the pure virtual function of the explanation.
