It is worth remembering that the copy constructor provided by the collection in Java supports onl

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
After the understands all the details behind implementing the Clone () method, you can create a class that can be easily replicated to provide a local copy:
: Localcopy.java//creating local copies with Clone () import java.util.*;
Class MyObject implements cloneable {int i;
MyObject (int ii) {i = II}
public Object Clone () {Object o = null;

When using Git for versioning, to get a copy of a project, we need to know the address of the project repository (the Git URL). Git can be used under many protocols, so Giturl may be ssh://, HTTP (s)://, git://, or just a username (which git would think is an SSH address) for the prefix . some warehouses can be accessed through more than one protocol, For example, the source code for git itself can be used to access the git:// protoco

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]
