With the development of computer technology and the popularization of computers, there are large and small "hacker" website and more and more simple tools, so that the current attacks become increasingly frequent, the computer or server embedded Trojans are more and more, at the same time the security awareness of the system administrator is also improving, plus anti-virus software development, The life cycle of the Trojan Horse is also getting shorter, so the attacker, after acquiring the contr
Section 5 clone [5] The object model in PHP5 calls an object through reference, but sometimes you may want to create a copy of the object and expect that the change of the original object will not affect the copy. for this purpose, PHP defines a special method called _ clone. like _ construct and _ destruct, the front has two underscores.
By default, the _ clone
All Java classes inherit the Java.lang.Object class by default, and there is a Method clone () in the Java.lang.Object class. The documentation for the JDK API explains that this method will return a copy of the object. There are two points to note: one is that the Copy object returns a new object, not a reference. Second, the difference between a copy object and a new object returned with the newly operator is that the copy already contains informati

Why is it like a shadow separation technique?
Refer to Naruto ):
The separation technique can be divided into several bodies, dozens of bodies, and even thousands of bodies.
(This is an enhanced version of Naruto's multi-shadow split-Body Technique-"Harem techniques 」)

PHP object-oriented clone
One of the biggest disadvantages of php4 object-oriented is to regard objects as another data type, which makes many common OOP Methods unusable, such as design patterns. These OOP methods depend on passing objects as references to other classes, rather than passing objects as values. Fortunately, PHP solved this problem. All objects are considered as references by default. However, because all object pairs are regarded as re
share the address space.
Do_fork checks clone_vfork. If this bit is set to 1, the child process locks the address space of the parent process until the child process exits or
The lock is released only when exec is executed.
Some concepts of threads are briefly introduced before calling the clone system.
A thread is further abstracted based on a process. That is to say, a process is divided into two parts: a thread set and a resource set. Thread

There is often such a requirement that a document contains too many content to be filled in, and sometimes multiple sub-documents are associated. Customers do not want to fill in the documents one by one. They want to copy data from existing documents, create a new record. This article describes how to clone a record, including its sub-documents, to generate a new record.

If you use "new"If you re-create an object with a keyword, assign the same attribute to it, which is cumbersome and error-prone.It is necessary to clone an identical object based on an o

To implement a clone, a class needs to implement the Cloneable interface, which indicates that the object of this class has the function of cloning. The Cloneable interface is an Mixin interface that does not have any abstract methods, similar interfaces have serializable interfaces, which indicate that objects of this class can be serialized. The concept of another object should be explicitly cloned from one object: By cloning another object from one
I implemented it myself:
Copy codeThe Code is as follows: public class A implements Cloneable {
Public String str [];
A (){Str = new String [2];}
Public Object clone (){A o = null;Try {O = (A) super. clone ();} Catch (CloneNotSupportedException e ){E. printStackTrace ();}O. str = new String [2];Return o;}}
Void run () throws Exception {A a1 = new A (), a2 = new ();A1.str [0] = "a"; a1.str [1] = "B ";A2 =

This article mainly introduces how to use the _ clone () method in PHP programming. the __clone () method is equivalent to a shortest copy, which is the basic knowledge in PHP beginners, you can refer to defining a _ clone () method in the object class to adjust the object cloning behavior. The code for this method will be executed during the Clone operation. In

Turn from: 78793300Prototype modeIn C + +, to copy an object, you can implement a clone function in addition to customizing a copy constructor for object replication. This requires the use of a compiler implementation of a hidden copy constructor, such a practice, more worry.The rationale behind this is the C + + prototype (Prototype) pattern: Specifying the kind of objects created with the prototype instance, and creating new objects by copying them.
Reprint: https://www.cnblogs.com/zouhao/p/7278117.htmlA: In JavaScript, if the cloned object is a basic type, we can assign it directly:1 var sStr = "Kingwell"; 2 var cStr = sstr;3 alert (cStr);//output KINGWELL4 SSTR = "ABC"; 5 alert (CSTR);//output Kingwell;When you assign a value to another variable, the value of that variable is not affected when it is changed.Two: If it's not the basic type, it's all different:1 var aarr = [0,1,2,3];2 var m = aarrr;3 alert (m);//Output 1,2,34 aarr=[3,2,1,0]
