So my branches are master develop_one develop_two When i use git clone git@bitbucket.org:project/project.git , i am getting only the master branch code, but i need to clone/pull only develop_one branch, so how to clone/pull only develop_one branch code ? Note: The other branches(develop_one, develop_two) are not merged in to master, and dont want to merge until the functionality has been completed actually, so want to get/clone/pull only a

问题 I implemented the copy constructor as it is described here. But still the problem is that when I update route_copy , then the same update is applied to route . So, I don't understand what is wrong in my code? public class Route implements Comparable<Route> { private List<Site> sites; public Route() { sites = new ArrayList<Site>(); } public Route(List<Site> sites) { this.sites = sites; } /** * Copy constructor */ public Route(Route r) { this(r.sites); } public void deleteSite(Site s) { this

问题 Introduction I have a Class Persons that contains an array of Person and functions : function Persons() { this.mItems = []; // Array of Objects Person } Persons.prototype = { calculateScores : function() { // Do some stuff } } The Class Person has members and functions : function Person(name) { this.name = name; // Name of the Person this.score = 0; } Person.prototype = { calculateScore : function() { // Do some stuff } } I want that the program does the following things : var persons = new

问题 I want to clone a <select> input in HTML using JQuery. I'm not sure how to go about it, so thought I'd ask here. Particularly interested in the best way to write it back into the document as well. My select element looks like this: <select id="options"> <option value="1">Opt 1</option> <option value="2">Opt 2</option> <option value="3">Opt 3</option> </select> Thanks. 回答1: See: http://api.jquery.com/clone/ $('select#options').clone().attr('id', 'newOptions').appendTo('.blah'); appendTo(...)

问题 I'm trying to clone a repository. The first time I got to 82%, then it didn't budge for half an hour so I cancelled the clone and started over. After that, every time I try to clone it, I get between 6-10%, and then it fails with the error "The remote end hung up unexpectedly, early EOF." I looked up the error and tried every solution I could find, with the most popular solution being to increase postBuffer to the maximum size. However, it still keeps failing every time. I'm not sure if it

问题 I am reading the mount & clone man page. I want to clarify how CLONE_NEWNS effects the view of file system for the child process. (File hierarchy) Lets consider this tree to be the directory hierarchy. Lets says 5 & 6 are mount points in the parent process. I clarified mount points in another question. So my understanding is : 5 & 6 are mount points means that the mount command was used previously to 'mount' file systems (directory hierarchies) at 5 & 6 (which means there must be directory

问题 I'm currently trying to get Netbeans with the Git plugin working. If I want to clone my git repository from within Netbeans I get the error message: reject hostKey: [repository url] and the cloning aborts. What does this mean and how do I fix it? 回答1: You need to check what user is running NetBeans, and then make sure your ssh private and public keys ( id_rsa and id_rsa.pub ) are in the associated HOME/.ssh of that user. Note that on Windows, HOME isn't defined by default, so you need to set

问题 I have several domain classes for which the user interface includes a "duplicate" command. As part of the implementation of those commands, I have implemented clone() methods in the corresponding domain classes. I have been trying to correct my bad habit of improperly implementing clone() (in general) based on use of " new " rather than "super.clone()," so as soon as I thought about doing the same for my Grails domain classes, I wondered how using super.clone() to obtain a clone might

问题 It's a shame for me, but I did not know that: You should use clone to copy arrays, because that's generally the fastest way to do it. as Josh Bloch states in this blog: http://www.artima.com/intv/bloch13.html I always used System.arraycopy(...) . Both approaches are native, so probably without going deeper into the sources of libraries I can not figure out, why it is so. My question is simple: why is it the fastest way? What is the difference with System.arraycopy ? The difference is

问题 I have an object $objDummy of some class ClassDummy and another is as $objClone = clone $objDummy; Then I make any change in $objClone , $objDummy is also changed. I do not want to do that. How can I get this to work? EDIT: In response to Chris. Here is an example <?php class myAnotherObject{ public $myAnotherVar =10; } class myObject { public $myVar = false; function __construct() { $this->myVar = new myAnotherObject(); } } $nl = "\n"; //* $nl = '<br />'; //*/ $obj1 = new myObject(); echo
