i getting error , when try "subnodes" added following code in class

  private list<subnodes> subnodes = new arraylist<subnodes>();

then getting error "expected string begin_array"

kindly me how can "subnodes" list

in bom.java

please add getter/setter method :

private list<subnodes> subnodes = new arraylist<subnodes>();  public list<subnodes> getsubnodes() {     return subnodes; }  public void setsubnodes(list<subnodes> subnodes) {     this.subnodes = subnodes; }

i have tried below .. working fine.

package com.brp.mvc.util;  import java.io.ioexception; import java.util.iterator;  import com.google.gson.gson; import com.google.gson.jsonarray; import com.google.gson.jsonelement; import com.google.gson.jsonparser;  public class gsonnodes {     public static void main(string[] args) throws ioexception {          try {             jsonelement je = new jsonparser().parse("[{\"subconfigid\":\"bac\",\"totalprice\":\"634.00\",\"bom\":{\"ucid\":\"ucid\",\"type\":\"rootnode\",\"attributes\":{\"visible\":true,\"price_status\":\"success\"},\"subnodes\":[{\"description\":\"enterprise shock rack\",\"ucid\":\"ucid\"},{\"description\":\"svc\",\"ucid\":\"ucid\"}]},\"breakdown\":{\"sv\":550.0,\"hw\":6084.0},\"currency\":\"usd\"}]");             jsonarray ja = je.getasjsonarray();             iterator itr = ja.iterator();              while (itr.hasnext()) {                 jsonelement je1 = (jsonelement) itr.next();                 gson gson = new gson();                 details details = gson.fromjson(je1, details.class);                  system.out.println(details.getsubconfigid());                 system.out.println(details.getcurrency());                 system.out.println(details.getbreakdown());                 system.out.println(details.gettotalprice());                 system.out.println(details.getbom().getucid());                 system.out.println(details.getbom().getsubnodes().get(0).getdescription());             }         } catch (exception e) {             e.printstacktrace();         }     } }

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...

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 ...
