java - Should we use clone or BeanUtils.copyProperties and why -

-

It looks - BeanUtils.copyProperties starts creating a clone of an object. If this is the case, And with concerns about implementing the clonable interface (only the new ones where there are references copied in computational objects), which is the best and why?

I made the cloning yesterday and then realized that I had to provide my own modifications for the non string / primitive elements, then I got the BeanUtils.copyProperties < / Code>, which I am now using. Both implementations provide similar functionality.

Thanks

Josh Block offers some quite good logic (provided by you Including one who made it) also said that the cloning is basically defective, rather than in favor of the copy constructor. See.

I have not used any practical use yet to make an immutable copy. You are copying the objects for a specific reason, possibly for the processing, to exclude some set of items that can be transformed into a single transaction, can not guarantee anything unless the processing unit is complete. If they are already immutable, then a reference is as good as a copy.

BeanUtils.copyProperties are often a less intrusive way of copying without supporting your classes, and it offers some unique flexibility in compositing objects.

That said, copyProperties do not always fit a size, all. You need to support certain types of objects at some points, who have special constructors, but are still unstable. Your objects can support internal methods or constructors to work around those exceptions, or you can register in some external devices to mimic specific types, but it can not reach some places which can be cloned ( ) can do. It's good, but still there are limitations.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

ios - Replace text in UITextView run slowly -

-
I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
