cloning

问题 I have next situation: Connection manager should have each time one object of ConnectionServer and new objects of DataBean So, I have created these beans and configured out it spring xml. <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org

问题 One core concept in Redux is, states are immutable. However, I saw many examples, including in Redux docs using javascript Object.assign. Then, I saw this warning in MDN: For deep cloning, we need to use other alternatives because Object.assign() copies property values. If the source value is a reference to an object, it only copies that reference value. So, why using Object.assign if the whole point is immutability? Am I missing something here? 回答1: Let's look at the example you linked:

问题 I have a project with a handful of submodules. Many of them are cloned from a GitHub fork to which I've added a branch for my custom mods. A typical setup is like thus: In local folder: MyProject1/Frameworks/SomeAmazingRepo/ $ git branch -vva *my-fork 123456 [my-fork/my-fork] Latest commit msg from fork master abcdef [origin/master] Latest commit msg from original repo remotes/my-fork/my-fork 123456 [my-fork/my-fork] Latest commit msg from fork remotes/my-fork/master abcdef [origin/master]

问题 I have an MVC3 application that needs to sync view models with database models. I found myself writing way too much code to copy properties back and forth between the different objects. I avoided this where I could simply subclass the data model, but at other times, I found that too restricting. I developed a few extension methods on Object to support shallow cloning of properties with similar names, and this has worked rather well. However, I'm wondering if there is a more efficient means to

问题 I need to implement a deep clone in one of my objects which has no superclass. What is the best way to handle the checked CloneNotSupportedException thrown by the superclass (which is Object )? A coworker advised me to handle it the following way: @Override public MyObject clone() { MyObject foo; try { foo = (MyObject) super.clone(); } catch (CloneNotSupportedException e) { throw new Error(); } // Deep clone member fields here return foo; } This seems like a good solution to me, but I wanted

问题 I'm developing an android app which use the com.rits.cloning and org.objenesis.* libs to deep clone object. The purpose is to add same object to my tree structure class twice or more without worrying that the original object is referencing to the same object. Since the regular clone() just shallow copy the object, I use the mentioned libs. Before develop the android project, I created a java project to implement my tree and it worked fine using those libs. Then I imported it to the android

问题 I am working on a shared server and trying to clone a virtual env myenv into my home directory . Here are some facts: myenv /path to my home directory/my profile/.conda/envs/myenv root * /opt/conda/4.6.14 I currently do not have permissions to install packages into the install area /opt/conda/4.6.14 and so I am trying to clone the myenv into my home directory using this command: conda create -n myenv_clone -p /path to my home directory/myprofile --clone=/opt/conda/4.6.14 However, this gives

问题 I've been using ArrayLists on a project of mine, and I need to create a default ArrayList so I can reset the original one whenever I want. So, I copy the original ArrayList to create the default one. However, whenever I modify something on the original, it also changes the default one. How can I make the copy "static" and unchangeable? Here is my code: (It's in portuguese) private ArrayList<Compartimento> listaCompartimentos; private ArrayList<Compartimento> listaCompartimentosDEFAULT; public

问题 I would like to merge an existing MTP (Master Test Plan) defined as a Test Suite with subfolders and TestCases, into another MTP (same structured), but located in a different project in TFS2017. The idea is to have both project sharing the same MTP, so any change can be visible in both projects. By now, I've just seen the existing possibilities about cloning/copying test cases between different test suites, but all of them should be part of the same project. I guess there must be an easy way

问题 I am trying to test my app in github. I had a friend of mine authorize my app to access private and public repos and that all went fine. Despite this for some reason i can't seem to clone his repos using the Oauth Token i got back after he authorized with my app. I cloned by using the instruction outlined in this link: https://github.com/blog/1270-easier-builds-and-deployments-using-git-over-https-and-oauth The out come in terminal looks like: Cloning into 'repoName... fatal: Authentication
