clone

I have a select box that gets cloned. I want to remove the user's previous selection from each cloned select box. Here is the method that does the clone() : function addselect(s){ $('#product_categories > .category_block:last').after( $('#product_categories > .category_block:last').clone() ); set_add_delete_links(); return false; } function set_add_delete_links(){ $('.remove_cat').show(); $('.add_cat').hide(); $('.add_cat:last').show(); $("#product_categories > .category_block:only-child > .remove_cat").hide(); } function removeselect(s){ $(s).parent().remove(); set_add_delete_links(); return

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 />'; //*/ $obj1 = new myObject(); echo 'obj1->myVar->myAnotherVar: '.$obj1->myVar->myAnotherVar; $obj2 = clone $obj1; echo $nl.'obj1->myVar-

I am cloning a form in jQuery mobile and the cloned form elements do not seem to work. IE the select lists do not change value, you cannot slide the range sliders. I'm trying to use the following code to clone a form and increment the name and id values on each instance of the cloned form. function newObservation() { var len = $('.observation').length; var titleLen = $('.observation').length + 2; var $html = $('.observationTemplate').clone(); $('.observationTitle:eq(0)').text("Observation - " + titleLen); $html.find('[name=audit-observation-category]').eq(0).attr({name:"audit-observation

I am trying to clone a (private) remote repository but I am getting following error: remote: Counting objects: 11410, done remote: Finding sources: 100% (11410/11410) remote: Getting sizes: 100% (9178/9178) error: RPC failed; result=56, HTTP code = 200 error: inflate: data stream error (invalid block type) fatal: pack has bad object at offset 427781: inflate returned -3 I am using Git version 1.9.4 on Windows 8 Pro Build 9200. There are large files on that repo, but file size seems irrelevant to my problem because I still get the same error when I try to clone some other smaller repository (

I'm trying to make a deep copy of an object, including a GregorianCalendar instance. I'm always wary of using clone() and it doesn't seem to have been overridden here, so I'm just doing the copy field by field. Ideally, there'd be a copy constructor, which I could use like so: GregorianCalendar newCalendar = new GregorianCalendar(oldCalendar); Unfortunately I can't find any such functionality in the API and am stuck trying to figure out which fields I need to get an exact copy. So, to make a copy of one of these calendars, how would you do it? Am I missing some simple shortcut here? java.util

Here is something that I cannot understand. In java.lang.Object the clone() is defined with protected modifier. By definition than it can be accessed by name inside its own class definition, by name inside any class derived from it, and by name in the definition of any class in the same package. Here the Sample class is in another package, and obviously it can't access clone() from the Object class. But as Sample derives implicitly from Object , why is it not able to access it? The definition doesn't say that it HAS to satisfy both conditions (inside same package AND also to be a subclass).

In Scala, does AnyRef.clone perform a shallow or deep copy? Short answer : shallow. Not-so-short answer : Unless it's overridden, AnyRef.clone() uses the Java's Object.clone() as its implementation. Javadoc on Object.clone(): The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable. Otherwise, this method creates a new instance of the class of this object and initializes all its

I have a hash like: h = {'name' => 'sayuj', 'age' => 22, 'project' => {'project_name' => 'abc', 'duration' => 'prq'}} I need a dup of this hash, the change should not affect the original hash. When I try, d = h.dup # or d = h.clone d['name'] = 'sayuj1' d['project']['duration'] = 'xyz' p d #=> {"name"=>"sayuj1", "project"=>{"duration"=>"xyz", "project_name"=>"abc"}, "age"=>22} p h #=> {"name"=>"sayuj", "project"=>{"duration"=>"xyz", "project_name"=>"abc"}, "age"=>22} Here you can see the project['duration'] is changed in the original hash because project is another hash object. I want the hash

I have an object that I need to copy in Java. I need to create a copy and run some tests on it without changing the original object itself. I assumed that I needed to use the clone() method, but this is protected. Having done some research on the net, I can see that this can be overriden with a public method in my class. But I cannot find an explanation on how to do this. How could this be done? Also, is this the best way of achieving what I need? ecleel Another option by using Copy Constructor (from Java Practices ): public final class Galaxy { public Galaxy (double aMass, String aName) {
