After cloning is complete, there may be a conflict with the MAC address, go to KVM to remove the eth0 configuration in/etc/udev/rules.d/70-persistent-net.rules, then change eth1 to Eth0, and modify/etc/sysconfig/ Network-script/ifcfg-eth0 Mac, confirm that the MAC address in the two configuration files is the same.Reference:http://blog.51cto.com/freedyong/1361907Modify MAC address after KVM clone is complete under CentOS/vmware copy virtual machine Mo

Undoubtedly, the launch of PHP5 has a profound significance for the development of network applications. This is not just because it is highly backward compatible with PHP4. Of course, PHP5 data packets have powerful object models and a set of new functions and libraries, not to mention its portable exception mechanism, which gives it the ability to effectively handle errors and abnormal events. Write files to the server using PHP Of course, when we use the word "function, we are talking about n

copy, deep copy creates a new object with the same (same content) fields in the original object. That is to say, this reference is different from the reference of the original object, when we change this field in the new object, it does not affect the content of the corresponding field in the original object. Shallow replication: The memberwiseclone method of the object class must be used to create a superficial copy for deep replication: the clone

Under what circumstances is a clone node used? We know that if you use the node directly during the DOM operation, the node will change with the operation. For example, the node is added to the new place, and the nodes in the original position are removed when using the. After/.before/.append method. Sometimes it is necessary to retain the original location of the node, just need a copy to add to the corresponding location, this time the

transmission is used, and when the input parameter is an object, reference transmission is used. Ii. Object clone In Java, if a copy object needs to be exactly the same as an object, it is wrong to assign values directly, because the value assignment operation passes the object reference, the clone method is the most efficient and convenient. To clone an object,

Programmers often misuse the copy constructors provided by each collection class as clones, List Set ArrayList HashSet or methods implemented by other collections. It should be remembered that the copy constructor for the Java collection only provides a shallow copy rather than a deep copy, which means that the objects stored in the original list and the clone list are the same, pointing to the same location in the Java heap memory. One of the reasons

1 protected native Object clone () throws Clonenotsupportedexception; 1. The method is modified by native keyword The native keyword in Java indicates that this method is a local method, "Java native description." Moreover, the native modified method performs more efficiently than native . 2. The method is modified by protected When a class overrides the Clone () method, it needs to be modified to the p

One of the advantages of the Java language is that it cancels the concept of pointers, but it also causes many programmers to ignore the differences between objects and references in programming, especially programmers who learn Java before C and C + +. And since Java cannot solve the problem of object duplication through simple assignment, in the development process, the Clone () method is often used to replicate objects. For example, when a function

Now clone is no longer a new word. With the advent of "Dolly", it is indeed a "fire" for a while. This concept also exists in Java, it allows us to easily create a copy of an object. Let's take a look at how the clone mechanism works in Java? 1. Clone copy assume that there is currently an employee object, which is employee Toby = new employee ("cmtober", 5000)

Deep copy of clone () in Java Show the shortest copy: for non-basic data types, after the clone, the two pointers point to the same memory space, so it is only a shortest copy, so if you operate on an object, the other content also changes, which is obviously unreasonable. Each object should save its own data. So we need to make a deep copy! Example of shortest copy and deep copy: Import java. util. vecto

Section 5-clone the object model in PHP5 to call the 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, use the _ clone
