i trying set variable callback tried $apply got error $apply conflicting, after research found out should use $timeout instead of $apply. changed code shown below. 

myapp.controller('dynamicctrl', ['$scope', '$timeout', function ($scope, $timeout) {       var jsonobj = [];      jsonobj.push({         "type": "text",         "model": "text",         "label": "text",         "placeholder": "text"     });      //$scope.stdformtemplate = jsonobj;     var ctx = new sp.clientcontext.get_current();     var web = ctx.get_web();     var list = web.get_lists().getbytitle('title');     var listfields = list.get_fields();     clientcontext.load(listfields);      ctx.load(listfields);     ctx.executequeryasync(function () {          onlistfieldsquerysucceeded(setjsondata);     },     function (sender, args) {         console.log(args);     });            function onlistfieldsquerysucceeded(callback) {         var type = "";         var fieldenumerator = listfields.getenumerator();         while (fieldenumerator.movenext()) {             var ofield = fieldenumerator.get_current();             var ftype = ofield.get_fieldtypekind();             if (ftype === sp.fieldtype.choice) {              } else if (ftype === sp.fieldtype.text) {              }           }          callback(jsonobj);     }            function setjsondata(jsonobj) {           $timeout(function () {             alert("hithere" +jsonobj);             $scope.stdformtemplate = jsonobj;         }, 0);      }      $scope.stdformdata = {};     $scope.urlformdata = {}; }]);

i trying achieve in function setjsondata, can see alert still $scope.stdformtemplate not getting updated expected.

i trying use this library.

i recommend using $q , promises. can externalize data access in factory/service , use promises handle async data access operations.

myapp.service('spaccess', function($q) {      this.getlistdata = function (listname) {          var deferred = $q.defer();            var ctx = sp.clientcontext.get_current();          var list = ctx.get_web().get_listbytitle(listname);          ctx.load(list);          ctx.executequeryasync(function() {             var items = [];             // data here             deferred.resolve(items);                          }, function(err, args){              deferred.reject([err, args});          });           return deferred.promise;      }; });  myapp.controller('ctrl', function(spaccess, $scope){     spaccess.getlistdata('my list').then(function(result){         $scope.items = result;     }, function(err){         console.log(err);     }); });  // note: code untested, , written on-the-fly, minor adjustments/fixes may neccesary.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
