c++ - How to generalize an iterator to a certain type -

-

Consider these two functions, which work well for std :: vector: 

  int ConnectNode (GraphNode const and newNode, std :: vector & lt; GraphNode const * & gt; :: launches const_iterator; candidates, std :: vector & GraphNode const *>: const_iterator endCandidates } {Int connections = 0; (Auto IARR = start candids; Iter! = And candidates; ++ Iter) {if (Connectododes (Hydrom, ** Iter)) ++ connection; } Return Connection; } Int connectNode (GraphNode const and newNode, std :: vector & lt; GraphNode & gt; :: const_iterator has been started, std :: vector & gt; GraphNode & gt; :: const_iterator endCandidates} {int connections = 0; (Auto IARR = Start Candidates; Iter! = And Candidates; ++ Iter) {If (ConnectNodes (Nodnod, * IAR)) ++ Connection;} Return Connection;}   
 These functions work well for vectors but not clearly for any vertical containers, eg a set. How to normalize them I can imagine that the only possible solution is that some pretty ugly enabled eef is temporarily. Is there a straight forward solution? Edit: To make it clear: I want both functions, for a normal containers, indicator container's The real logic is inside the connetNodes, which has two references. (Previously the brain in work)   
 
 
 As it was said, type the Iterator a temple T parameter - This iterator fixes the issue of normalization, for the difference between normal  GraphNode , and its indication, you can use overloading:  
  Template & lt; Class T & gt; T & amp; Maybe_dirref (T & amp; amp) {return V; } Template & lt; Square T & gt; T & amp; Maybe_Dirfe (T * P) {Return * P; }   
 and just call it in the  connectNodes (new node, maybe_dirf (* enter)) .

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...
