clone

问题 I have read through the various posts for this problem and I can verify that using a -t when performing a remote ssh command does indeed force tty allocation and allow for command completion. However, the problem I am having is that twelve hours prior to this point I had trouble free access to this server. Now, with no known changes, I can no longer connect. I can login to this server all day long without a problem. However, when I try to execute a remote command, say ssh servername 'ls /var

问题 I'm using clone(true, true) to copy a select and some buttons to clone and remove. I thought the second true argument should ensure that the event handler is passed on to the cloned child buttons. Here is the markup: <div id="clone-container"> <div class="clone"> <label for="select1">Select 1</label> <select id="select1" name="select1" class=""> <option>Select One:</option> <option value="1">1</option> </select> <span class="controls"> <a href="#" class="btn add">+</a> <a href="#" class="btn

问题 I'd like to clone the second half of my repo. It works correctly using the command: git-p4 clone --detect-branches //depot@all So I want to run something like below, but it does not import the files the same way and eventually fails: git-p4 clone --detect-branches //depot@2000,3000 How can I get the second method to work correctly? Update : The output I get right now is that p4 becomes stuck in an infinite loop: current change 32688 trying: earliest latest

问题 I have never seen clone() method put to use in any real code. I was reading about it and felt that its use could make the code very cumbersome. is there any specific use case for the clone() method? Under what circumstances would one have to use clone() and why would the use of normal conctructor not suffice? 回答1: clone is very convenient to make defensive copies of arrays passed to methods or constructors (as all array types are Cloneable , and the signature for clone() is covariant so that

问题 I'm trying to implement an Undo/Redo stack in a C# application that I'm working on by restoring an Object to a previous state when undo is called. I have an 'Action' class which looks basically like this: class Action { object old_state; object new_state; public Action(object old) { old_state = old; } public void finish(object new_obj) { new_state = new_obj; } public void reverse() { new_state = old_state; } } When an action is started that can be redone, a new action is created. When we

问题 I have an enumeration, Fruit , and a class, FruitCollection , which derives Collection<Fruit> . I couldn't find a way to clone FruitCollection using .NET and I found this MSDN article which defined a DeepClone() function and used MemberwiseClone() . Now, since this is an enumeration, I don't think I need to "deep" clone it, so I thought MemberwiseClone() would be sufficient. However, when I try it in PowerShell, the cloned object seems to simply be a pointer to the original object and not a

问题 I have a Git repository with a lot of history. I'd like to make this accessible to others, but one of the directories in it contains proprietary code that can't be distributed. Is there any way I can make a clone of the repository (with history) that excludes that directory? Bonus: I'd also like to be able to merge changes to the 'public' code made in the old, main repository into the clone. 回答1: You cannot do that unless you are willing to rewrite each commit hash. If you decide to rewrite

问题 I'm trying to clone a select2 list and 2 text areas, but it's working only for the first clone, and I don't understand why..any new eye will certainly help ! (the cloning is OK, but the select2 is not applied to the 3rd clone) HTML part <fieldset> <div id="test"> <div> <label>Tool Name : </label> <select class="toollist" name="FSR_tool_id[]" style="width: 350px" /> <option></option> <option value="1" >bla 1</option> </select> <input type="Button" value="ADD ANOTHER TOOL" class="AddTool">

问题 Here is my playground snippet: class Box { func clone() -> Box { return Box() // <- how to return superclass here? } } class VBox:Box { } let vb = VBox() let cBox = vb.clone() // now cBox is a Box, not a VBox My clone function returns a Box class in all cases. But for the subclass I want it to return the superclass (so above it should return VBox ). I know I could override the clone function inside VBox but I wonder if there's a smarter way. 回答1: You mean subclass. Box is the superclass,

问题 So I'm using the git clone command but when I try to clone the repository into a specific folder it doesn't create a folder like it does normally. For example when I use it like this git clone https://github.com/username/repositoryName.git it creates a folder named repositoryName and stores the repository in there. When I'm using it like this git clone https://github.com/username/repositoryName.git myFolderName it doesn't create that default folder it would create. It just saves it in
