When a subclass needs to invoke a method of the parent class, the method of the class is invoked directly with the class name before the python2.2, that is, the unbound class method, and the Self object self as an argument is passed in. Class A (object): def Say (self): print ' I am A ' Class B (a): def Say (self): print ' I am B ' A.say ( Self) B = B () B.say () Output I am B I am A This works fine, but there is a problem, when the paren

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a typical three-layer switch, the communication between broadcast domains is usually impleme

java keyword This, super use summary First, this The Java keyword This can only be used in a method method body. When an object is created, the Java Virtual Machine (JVM) assigns a pointer to the object that refers to itself, which is the name of this pointer. Therefore, this can only be used in non-static methods in the class, static methods and static code blocks must never appear in this, which is explained in the article "Java keyword static, fin

First of all, we have a question about the Python super class in StackOverflow as the beginning of this article, the problem is basically this:>>>classA (object): ...def __init__(self): ...Print "A Init"... super (a,self) .__init__()... >>> >>> A =A () a init>>>classB (object): ...def __new__(self): ...Print "B New"... super (b,self) .__new__()... >>> >>> B =B ()

The principle of Super VLAN aggregation, which is no longer difficult to understand, is also mainly used in the network of service providers to solve the shortage of IPv4 address resources. A Super VLAN is also known as VLAN Aggregation. The principle is to set a Super VLAN and multiple Sub VLANs (subvlans) association (similar to the Isolate-user-VLAN mentioned

PHP has built in some super global variables that we can use and visible anywhere in the script, and we'll take a look at these global variables:1, $_serverThe $_server Super global variable contains information created by the Web server that provides information about the server and client configuration and the current request environment. Depending on the server, the variable value and the number of varia

Super is used to solve multiple inheritance problems, it is not a problem to call the parent class directly with the class name when using single inheritance, but if multiple inheritance is used, it involves various problems such as lookup order (MRO), repeated invocation (Diamond inheritance). In short, the experience left behind is: to maintain consistency. Either call the parent class with the class name, or use

Note: python3 is the runtime environment. The example is taken from Chapter 8th of pythoncookbook. In python, there are two main methods to initialize the parent class if the subclass is to be implemented. The first method is to directly use the parent class name, and the second method... quot; gt; lt; metaname quot; keywords quot; content quot; call details of pythonsuper in multi-inheritance. note: python 3 is the runtime environment, the example is taken from Chapter 8th of python cookb

Two special variables in Java: this and super -- general Linux technology-Linux programming and kernel information. The following is a detailed description. There are two very special variables in Java: this and super. These two variables do not need to be declared before use. This variable is used inside a member function and points to the current object. The current object refers to the object that calls

Java static, this, super, final usage I. Static Take a look at the following program: Public class Hello {Public static void main (string [] ARGs) {// (1)System. Out. println ("Hello, world! "); // (2)}} I have read this program, and it is no stranger to most of them who have passed Java mathematics. Even if you have never learned Java and other advanced languages, such as C, you should be able to understand the meaning of this Code.

Mro Method resolution order is used by python to parse the method call sequence. Mro is important for method calling in Multi-inheritance. There is a built-in function in Python that is closely related to Mro-Super. As the name suggests, super should look like a method to call the parent class, which is usually the same. Let's look at a piece of code: Class A (object): Here we use
