c# - Method To Set Nested Property Value -


i'm writing plugin piece of software requires code in single class (or nested classes)...

what i'm wanting create method can handle changes nested properties of _data object , give me central place things setting dirty flag know save later.

below code illustrating file's structure , @ bottom 2 pseudo-methods can give idea of i'm trying accomplish.

public class someplugin {     private dataobject _data;     private bool _dataisdirty = false;      private class dataobject     {         public generalsettings settings { get; set; }     }      private class generalsettings     {         public string settingone { get; set; }         public string settingtwo { get; set; }     }      protected override void init()     {         _data = new dataobject         {             settings = new generalsettings             {                 settingone = "example value one.",                 settingtwo = "example value two."             }         }     }      // these pseudo-methods illustrating i'm trying do.     private void setdata<t>(t ref instanceproperty, t newvalue)     {         if (newvalue == null) throw new argumentnullexception("newvalue");         if (instanceproperty == newvalue) return;          instanceproperty = newvalue;         _dataisdirty = true;     }      private void someothermethod()     {         setdata(_data.settings.settingone, "updated value one.");     }  }

consider approach like:

public class someplugin {     private dataobject _data;     private bool _dataisdirty = false;      public bool isdirty => _dataisdirty || (_data?.isdirty ?? false);      private class dataobject     {         private bool _dataisdirty = false;          public bool isdirty => _dataisdirty || (settings?.isdirty ?? false);         public generalsettings settings { get; set; }     }      private class generalsettings     {         public bool isdirty { get; set; }          private string _settingone;          public string settingone         {             { return _settingone; }             set             {                 if (value != _settingone)                 {                     isdirty = true;                     _settingone = value;                 }             }         }          public string settingtwo { get; set; } // won't mark dirty     } }

note in particular settingone has logic in setter determine whether set isdirty or not.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
