clone

Anybody have a good example how to deep clone a WPF object, preserving databindings? The marked answer is the first part. The second part is that you have to create an ExpressionConverter and inject it into the serialization process. Details for this are here: http://www.codeproject.com/KB/WPF/xamlwriterandbinding.aspx?fid=1428301&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2801571 The simplest way that I've done it is to use a XamlWriter to save the WPF object as a string. The Save method will serialize the object and all of its children in the logical tree. Now you can create a new

I have an object which has many bufferedimages in it, I want to create a new object copying all the bufferedimages into the new object, but these new images may be altered and i don't want the original object images to be altered by altering the new objects images. is that clear? Is this possible to do and can anyone suggest a good way to do it please? I have thought of getSubImage but read somewhere that any changes to the subimage are relected back to the parent image. I just want to be able to get a fresh entirely separate copy or clone of a BufferedImage Something like this? static

This code ( playground ): #[derive(Clone)] struct Foo<'a, T: 'a> { t: &'a T, } fn bar<'a, T>(foo: Foo<'a, T>) { foo.clone(); } ... does not compile: error: no method named `clone` found for type `Foo<'a, T>` in the current scope --> <anon>:7:9 |> 16 |> foo.clone(); |> ^^^^^ note: the method `clone` exists but the following trait bounds were not satisfied: `T : std::clone::Clone` help: items from traits can only be used if the trait is implemented and in scope; the following trait defines an item `clone`, perhaps you need to implement it: help: candidate #1: `std::clone::Clone` Adding use std:

java.util.Calendar.clone() returns "...a new Calendar with the same properties" and returns "a shallow copy of this Calendar". This does not appear to be a shallow copy as answered here on SO. That question is tagged language-agnostic, Java does not seem to follow the language agnostic definition. As I step through the code I notice that the structure and the elements are copied to this new object, more than the language agnostic structure only. In Java, what is a shallow copy? How does it differ from a Java deep copy (if that exists)? KitsuneYMG A shallow copy just copies the values of the

The Ruby docs for dup say: In general, clone and dup may have different semantics in descendent classes. While clone is used to duplicate an object, including its internal state, dup typically uses the class of the descendent object to create the new instance. But when I do some test I found they are actually the same: class Test attr_accessor :x end x = Test.new x.x = 7 y = x.dup z = x.clone y.x => 7 z.x => 7 So what are the differences between the two methods? Subclasses may override these methods to provide different semantics. In Object itself, there are two key differences. First, clone
