mirror

//方案一： public class Solution { public void Mirror(TreeNode root) { if(root==null) return; TreeNode temp=root.left; root.left=root.right; root.right=temp; Mirror(root.left); Mirror(root.right); } } //方案二： import java.util.*; public class Solution { public void Mirror(TreeNode root) { if(root==null) return; Stack <TreeNode> stack = new Stack<TreeNode>(); stack.push(root); while(!stack.isEmpty()){ TreeNode cur=stack.pop(); if(cur.left!=null||cur.right!=null){ TreeNode temp=cur.left; cur.left=cur.right; cur.right=temp; } if(cur.left!=null) stack.push(cur.left); if(cur.right!=null) stack.push(cur

Here is what I would like to do: Have a local git repository that mirrors an upstream one Be able to push "local" branches / changes to that repository and keep those locally Keep this repository in sync with the upstream one, including: Fetch any new branch Delete any reference of branches that are deleted upstream I setup my cron job to fetch all the changes from upstream and prune any branch that have been deleted like this: */5 * * * * cd /home/git/myrepo.git && git fetch origin && git remote prune origin > /dev/null So far what I have tried (and why it failed): 1- Setup the git repository

I want to change the Gitlab mirroring settings for each of my repositories. Is it possible to do this over the Gitlab API? The options the Gitlab WebUi allows, are the following: How can I change them via the API? Remark: This is not the same question as "How can I tell Gitlab to mirror my Github repositories over the API?" as there my question was how to start the mirroring, here I want to know how I can change the mirroring settings. On https://docs.gitlab.com/ee/api/projects.html#edit-project there are several parameters to configure the pull mirroring: > mirror > mirror_user_id > mirror

In Swift 4, is it possible to find all types within the current module which adhere to a specific protocol? For instance, say I've defined this protocol and these classes: protocol Animal{} protocol Vehicle{} protocol Favorite{} class Dog : Animal{ } class Cat : Animal, Favorite{ } class Car : Vehicle{ } class Bicycle : Vehicle, Favorite{ } I want to find all types that implement Favorite . This can be easily done in C#, but I’m not sure if you can in Swift. Cat Bicycle If it helps, I'm using Swift 4. I don't believe Swift currently has a 'native' (not dependant on the Objective-C runtime) API

From the docker distribution document: https://github.com/docker/distribution It says to configure the docker to use the mirror, we should: Configuring the Docker daemon You will need to pass the --registry-mirror option to your Docker daemon on startup: docker --registry-mirror=https://<my-docker-mirror-host> daemon I'm newbie to docker, and I start docker from mac normal by the provided "Docker Quickstart Termial" app, which actaully invokes a start.sh shell: #!/bin/bash VM=default DOCKER_MACHINE=/usr/local/bin/docker-machine VBOXMANAGE=/Applications/VirtualBox.app/Contents/MacOS/VBoxManage

使用容器技术搭建apt镜像站（apt-mirror-http-server） 使用Docker构建自己的 APT(Advanced Packaging Tools) 镜像站HTTP服务器。 源码： https://github.com/openthings/apt-mirror-http-server 1、创建镜像站点 1.1 基本命令 docker run -d --name aptmirror \ -v $(pwd)/aptdata:/var/spool/apt-mirror \ -p 9090:80 openthings/apt-mirror-http-server -v $(PWD)/data : 存储数据的目录。 1.2 使用docker 命令时更多选项 -v /path/your/mirror.list:/etc/apt/mirror.list : 用于替换 Ubuntu default mirror.list -e RESYNC_PERIOD=timeout-value : 设置 resync 同步周期, 缺省是 12 小时。设置 TIMEOUT format description 。 2、使用镜像站点 2.1 web访问 输入： http://127.0.0.1:9090 。刚建立时数据同步需要一些时间，显示是空的目录，过一段时间就可以使用了

When accessing the inner structure of a subclass of NSManagedObject using a Mirror, all managed variables are ignored. public class Foo: NSManagedObject { @NSManaged var bar: String? } var f: Foo = ... // ... creating a Foo in a valid context ... let mirror = Mirror(reflecting: f) for c in mirror.children { // children count == 0 print("\(c.label!):\(c.value)") // never executed } How can reflection mechanisms used on NSManagedObjects. The accessor methods for Core Data properties are synthesized dynamically at runtime. You can enumerate the attributes of a Core Data entity using the entity

用过 Sketch 的朋友应该都知道一个叫 Mirror 的功能，它可以将你的设计稿放到手机上预览，为设计师们提高了不少效率。而今天我要介绍的 jimu Mirror ，和 Sketch Mirror 类似，可以将 Android 的 xml 实时放到手机上预览。但是现代化的 IDE 都已经提供在 IDE 内实时预览 xml 的功能， jimu Mirror 有啥用呢？ 有用！还是相当有用！ 本文将以微信的界面作为参考，在不写一句 Java 代码的情况下，轻松实现微信的几个界面。 转载自我的博客： http://www.specyci.com/articles/16 1. 安装 jimu Mirror jimu Mirror 支持 Android Studio / IDEA，本文将以 Android Studio 作为开发环境，读者请自行下载对应版本。 http://jimulabs.com/mirror-downloads/ 将插件下载下来后，在 Android Studio 菜单进行简单操作，即可安装。 Configure -> Plugins -> install plugin from disk 没什么意外的话，你应该就能看见 Mirror 的小图标了。：） 2. 配置 jimu Mirror 如果你使用的是 Android Studio，恭喜你，你什么都不用做
