clone

I have created a Node ( AnchorPane ) in the JavaFX scene builder and was wondering how to clone it. I saw Duplicate/Clone Node in JavaFX 2.0 but I need to clone the Node without re-loading the fxml. Is there any way to achieve this in JavaFX 2? You can place the component that needs to be duplicated in a separate .fxml file. Then you can load the separate file as many times as needed adding the nodes to the appropriate root in the main scene. Additionally you can edit an <fx:include source="..."/> element to the main .fxml file and include the separate .fxml file. You can then still work with

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? 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 that variable before running Netbeans. 来源： https://stackoverflow.com/questions/6986617/netbeans-git-reject

I have a prescription model in my Rails 3 application. I am trying to work out the best method of allowing records to be duplicated, but allowing the user to "review" the duplicate before it's saved. I have read a number of questions/answers on SO (such as this one) which explain how to duplicate/clone the record and then save it - but none which explain how to show the form before save. Reading the Rails API is appears the clone method is available. Reading other questions and answers shows that is can be done but there is no example code apart from: new_record = old_record.dup The controller

The clone paradigm is used to make a copy of a derived class without casting down to the base class type. Unfortunately, clone must be implemented in each subclass (or with a mixin with CRTP). Is there any chance that C++11's decltype makes this unnecessary? I don't think the code below actually copies original , but simply points a reference to it. When I tried to use new decltype(*original) , I get an error: error: new cannot be applied to a reference type . Is clone still the way to go in C++11? Or is there some new way to use RTTI to copy a derived class object from a base class pointer?

I am learning concurrency and want to clarify my understanding on the following code example from the Rust book . Please correct me if I am wrong. use std::sync::{Arc, Mutex}; use std::thread; use std::time::Duration; fn main() { let data = Arc::new(Mutex::new(vec![1, 2, 3])); for i in 0..3 { let data = data.clone(); thread::spawn(move || { let mut data = data.lock().unwrap(); data[0] += i; }); } thread::sleep(Duration::from_millis(50)); } What is happening on the line let data = data.clone() ? The Rust book says we use clone() to create a new owned handle. This handle is then moved into the

I have a builder class which I am using in one of my project. Let's say I have metricA as builder based on below class. I need to make a new builder metricB based on metricA by cloning metricA so that metricB contains all the values which were already there in metricA . In the constructor of MetricHolder I am initializing some fields (which are not set directly) basis on fields that have been set already. clientTypeOrPayId - I am initializing this field. If payId is present, then I will set this value or I will set clientType . clientKey - I am initializing this field as well in the same

This question already has an answer here: How do I do a deep copy of a 2d array in Java? 6 answers I have two multidimensional arrays (well actually they're only 2D) which have inferred size. How do I deep clone them? Here's what I have gotten so far: public foo(Character[][] original){ clone = new Character[original.length][]; for(int i = 0; i < original.length; i++) clone[i] = (Character[]) original[i].clone(); } A test for equality original.equals(clone); spits out a false. Why? :| /**Creates an independent copy(clone) of the boolean array. * @param array The array to be cloned. * @return

Suppose I have an int-array and I want to modify it. I know that I cannot assign a new array to array passed as parameter: public static void main(String[] args) { int[] temp_array = {1}; method(temp_array); System.out.println(temp_array[0]); // prints 1 } public static void method(int[] n) { n = new int[]{2}; } while I can modify it: public static void main(String[] args) { int[] temp_array = {1}; method(temp_array); System.out.println(temp_array[0]); // prints 2 } public static void method(int[] n) { n[0] = 2; } Then, I tried to assign an arbitrary array to the array passed as parameter

I want to execute the following command on a remote server: git archive --prefix="$tag/" --remote="ssh://$gitserver/var/git/$repo" "$tag" | tar -xvf- The problem is I don't know what $tag is. It should be the output of git describe --abbrev=0 on an up-to-date clone, but I don't know how to get that information without making a local clone of the repository. Is it possible to do this without making a local clone? The only way you could start parsing for your tag, without adding too much to your local disk, would be: make an empty repo add the remote address of your remote repo try a git fetch -
