that GitHub gives more than one address and can also use such an https://github.com/michaelliao/gitskills.git address. In fact, GIT supports a variety of protocols, git:// using SSH by default, but can also use https other protocols.With the https exception of slow speed, one of the biggest problems is that each push must enter a password, but in some companies that only open HTTP ports, the protocol cannot be used ssh https .SummaryTo clone a warehouse, you must first know the address of the w
objects without interfering with each other.
_ Clone usage
In many cases, we do not only need to clone an object, but also want the object to have its own attributes and methods. Then we need to create a _ clone method in the class. This method is similar to constructor and Destructor because it is not called directly.
Take the preceding example as an example:
Name = $ name; $ this-> location = $ location;} function _ clone () {$ this-> location = 'Order up';} function play () {// create meth

The object model in PHP5 invokes the object by reference, but sometimes you might want to make a copy of an object, and you want the original object to change without affecting the copy. For this purpose, PHP defines an extraordinary method, called __clone. Like __construct and __destruct, there are two underscores ahead.
By default, the __clone method will establish an object that has the same properties and methods as the original object. If you want to change the default content when

1. Problem Description
Cloning virtual machines in VMware is a common issue. You can directly clone virtual machines that use winows as the client. The network cannot be started after the client is cloned from a Linux virtual machine.
When you run the service network start command, the following error occurs:
Device eth0 does not seem to be present2. Cause Analysis
Using the clone function of VMware, a new virtual machine is configured with a NIC
If there are similarities, we will be honored. If you reprint them, please noteIn C #, we will talk about using hashtable, datatable, and other copies and clones. Let's look at the example below.Hashtable ht = NULL;Ht = new hashtable ();Foreach (string s in HT){//... }// The key value in hashtable needs to be modified during the previous traversal. Generally, an exception is reported, prompting you that the set has been changed to XXX or something, because the set after in cannot be changed duri
Therefore, if you want to create an object with the same content as an existing object, you cannot simply assign values. This may be hard to understand.See the following example:Copy codeThe Code is as follows:Var a = [1, 2, 4]; var B = a; c = B;. pop (); // remove the last element alert (B); // pop up 1, 2, 3 alert (c); // pop up 1, 2, 3Var a = [1, 2, 4]; var B = a; c = B;. pop (); // remove the last element alert (B); // pop up 1, 2, 3 alert (c); // pop up 1, 2, 3 The code above shows that aft
