javascript - Filtering data based on dynamic check box Categories in Angular JS? -

-

i'm trying achieve filter check box option dynamic data category , sub category.

how want is,

[] category   [] sub category   [] sub category [] category   [] sub category   [] sub category   [] sub category   ... , on

assume [] check box above.

here's sample json data :

  [     {        "category": {           "name": "aaa - 1"        },        "parentcategory": {           "name": "aaa"        },        "title" : "xxxxx",     },     {        "category": {           "name": "aaa - 2"        },        "parentcategory": {           "name": "aaa"        },        "title" : "yyyy",     }  ]

based upon above data, i'm trying want is,

sidebar : 

[] aaa   [] aaa - 1    [] aaa - 2

main content :

initially show title. after checked, show title related category/sub category.

note : pl don't think i'm asking without effort. i've seen examples in jsbin, couldn't find wanted achieve. btw i'm new angular.

if understand correctly want that: http://jsfiddle.net/ms403ly8/67/

firstly found first parent item json array. found parent's children , add it. 

     angular.foreach($scope.itemlist, function(itm) {         var filtereditem = $filter('filter')($scope.itemlist, { parentcategory: itm.parentcategory.name});             if($filter('filter')($scope.parentitems, { name: itm.parentcategory.name}).length == 0){                 $scope.parentitems.push({name: itm.parentcategory.name, children:filtereditem});             }      });

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.
