android - How can I retrieve the values of parent as well as child using the same getValue(user.class) method from firebase? -


i want retrieve data parent child node @ same time in model class. example:

students: {       student1: {             id: 1,             name: "sam",             regno: "15001"               1stsmester: {                       c: 70,                      datastructures:80,                       },               2ndsemester: {                         cplus:85,                         sql:68                       }                  }       student2: {               id:2,               name:"rob",               regno:"15002"                 1stsemester: {                        c:59,                       datastructures:77                          },                  2ndsemester: {                         cplus:60,                         sql: 85                           }                   }

so, question how retrieve data student1 , student2? so, parents values 1stsemester , 2ndsemester child values 2 separate objects , map own model class.

thank in advance help.

make student , semester class

class students { int id; string name, regno; semester semester1, semester2;   public semester getsemester1() {     return semester1;     }    ... }  class semester {     string coursename;     double result; }

update

inner class has declared outside , setters , getters have set inner class objects.

call data 

  firebasedatabase.getinstance().getreference().child("students")     .addvalueeventlistener(new valueeventlistener(){   @override    public void ondatachange(datasnapshot datasnapshot){     if(datasnapshot.exists()){     arraylist<student> allstudents=   (arraylist<student>)datasnapshot.getvalue();     }     @override     public void oncancelled(databaseerror databaseerror){      }     });     }

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
