invented cloning

Hot clones, also known as Live clones or online clones, require that the source computer be converted during the process of running its operating system on the source computer. With hot cloning, you can clone a computer without shutting down the computer. Because the process continues to run on the source computer during the conversion, the resulting virtual machine is not an exact copy of the source computer. When you convert a Windows source, you ca

Why cloning is requiredIn the actual programming process, we often encounter this situation: there is an object A, in a moment a is already included in a number of valid values, it may be necessary to a exactly the same new object B, and then any changes to B will not affect the value of a, that is, A and B is two separate objects, But the initial value of B is determined by the A object. In the Java language, the use of simple assignment statements i

Virtual machine under the cloning of Linux virtual machine causes the cloning of the Internet problem!because the virtual machine cloning causes the system to retain the original NIC information and the clone of the new virtual network card is duplicated, because the system configuration file only recognizes eth0 this virtual network card, and ifconfig-a view of

First, shallow cloning: In a shallow clone, if the member variable of the prototype object is a value type, a copy is copied to the cloned object, and if the stereotype object's member variable is a reference type, the address of the referenced object is copied to the cloned object, that is, the prototype object and the member variable of the cloned object point to the same memory address. In simple terms, in a shallow clone, when an object is replica

content.Let's take a look at the following situationfunction SetObject (obj,newobj) {var newObj = NEWOBJ | | {};for (var i in obj) {if (typeof obj[i] = = ' object ') {Newobj[i] = (Obj[i].constructor = = = = Array)? [] : {}SetObject (Obj[i],newobj[i])}else{Newobj[i] = Obj[i]}}return NEWOBJ;}var tem2 = setobject (template);Tem2.user= "Shaw";Tem2.password = "123";Tem2.tem.push (' music ');var tem3 = setobject (template);Tem3.user= "Liu MoU";Tem3.password = "123456";Tem3.tem.push (' Sports ');Conso

, City: ShijiazhuangThe information for employee 1 is:Name: Zhagnsan, Age: 17, Address: Country: Zhongguo, Province: Hebei, City: Shijiazhuangand really want the result, employee 1 of information should not change. Employee 1 The reason for the change is that shallow cloning is not enough to clone a reference type, so deep cloning is needed to make the following adjustments to the code:1, address also need

This involves two classes, one for the person class and one for the test classThe first thing we're talking about is shallow cloning, which is completely unknown to an object when it's being cloned, it's simply a copy of domain-to-domain, and if it's a basic data type (INT,FLOAT,CHAR, etc.) to nothing, it's basically like a string, There is no problem with immutable objects such as Integer, but if you encounter a mutable object of date, or a mutable o

object ③ if the Equals () method of object x is properly defined, then X.clone (). Equals (x) should be set up. cloning of objects in ⑵java ① in order to get a copy of the object, we can take advantage of the Clone () method of the Class object. The ② overrides the Clone () method of the base class in a derived class and is declared public. The ③ calls Super.clone () in the Clone () method of the derived class. The ④ implements the Cloneabl

Php Object cloning method, php Object cloning This example describes how to clone objects in php. Share it with you for your reference. The details are as follows: I hope this article will help you with php programming.

We know that objects are divided into reference types and value types. Shortest: copy an existing object and point the reference type to the same memory block. (string is the most special object. Here we use it as the value type first) public class User { public int Age { get; set; } public string UserName { get; set; } public ListShallow copy code The output values are: 1 (user. List. Count (), which indicates the reference type. Let's look at the output below) Lisi 1
