clone

I don't understand the mechanism of cloning custom object. For example: public class Main{ public static void main(String [] args) { Person person = new Person(); person.setFname("Bill"); person.setLname("Hook"); Person cloned = (Person)person.clone(); System.out.println(cloned.getFname() + " " + cloned.getLname()); } } class Person implements Cloneable{ private String fname; private String lname; public Object clone() { Person person = new Person(); person.setFname(this.fname); person.setLname(this.lname); return person; } public void setFname(String fname) { this.fname = fname; } public void

I tried to clone an object and change member functions of new clonned object. If it is shallow copy and according to wiki page, shallow copy and original object point to same object then , it should change the variable value. CloneExample obj1=new CloneExample(); CloneExample obj2=(CloneExample) obj1.clone(); obj1.a=2; obj1.c='a'; System.out.println("obj1 real "+obj1.a+" "+obj1.c); System.out.println("obj2 real "+obj2.a+" "+obj2.c); obj2.a=99; obj2.c='z'; System.out.println("obj2 after change "+obj2.a+" "+obj2.c); System.out.println("obj1 after change "+obj1.a+" "+obj1.c); System.out.println(

I'm trying to clone a droppable object using Jquery but the cloned object is not droppable. $(document).ready(function(){ $("input[value='Add']").click(function(e){ e.preventDefault(); $("div.field:last").clone().insertAfter("div.field:last"); }); $(".field").droppable(); HTML <div class="field"> Last Name<input type="text" value="" /> First Name<input type="text" value="" /> </div> <div class="field"> Last Name<input type="text" value="" /> First Name<input type="text" value="" /> </div> <input type="Submit" name="submit" value="Add" /> Firebug shows that the cloned object has the class ui

Update: I think this is related to an issue with the windows git client msysgit. Sorry to trouble you guys. http://code.google.com/p/msysgit/issues/detail?id=379&colspec=ID%20Type%20Status%20Priority%20Component%20Owner%20Summary I'm looking for a way to keep several client boxes in synch with a remote git repo. Forcing updates from the remote repo and abandoning anything that may have changed on the client boxes. The problem I'm running into is that the client boxes will modify some of the files (installation logs etc.) and gives me a merge nightmare when I need to update them from the remote

I am not sure about the meaning of "...but not the objects they reference" in both the documantion of ruby and rubinus . In ruby-doc , there is the explanation of #clone and #dup behavior saying: Produces a shallow copy of obj—the instance variables of obj are copied, but not the objects they reference. Copies the frozen and tainted state of obj. See also the discussion under Object#dup. The same is repeated in the implementation of Rubinius : Copies instance variables, but does not recursively copy the objects they reference. Copies taintedness. I tried out with the following code, but the

There seems to be a bug still present in jQuery 1.6.2 that has an issue with .clone() and .html(). I created a fiddle: http://jsfiddle.net/Vxyu3/12/ that should help explain the bug. If you click on both links one after another, in Firefox the content will flip back and forth with no problems. In IE however (particularly IE7) if you go to the fiddle and then hit "Show Dynamic Content" then "Show Clone" then "Show Dynamic Content" then "Show Clone", the clone content is no longer visible. In fact it's not even injected into the DOM. It's like it disappears, or get erased somewhere along the way

I have problems with my keyup binding when cloning an element. Here's the scenario: I have an html markup like this: <tr class="rijbasis"> <td> <input type="text" class="count" /> </td> <td> <span class="cost">10</span> </td> <td> <span class="total">10</span> </td> </tr> I'm binding an keyup function to the input element of my table row like this: $('.rijbasis input').keyup(function(){ var parent = $(this).parent().parent(); $('.total',parent).text(parseInt($('.cost',parent).text()) * parseInt($('.count',parent).val())); } I designed the function like this so I could clone the table row on a
