javascript - Array attribute of scope in directive is emptied upon reference -

-

my directive looks this:

angular.module('app')   .directive('chart', function () {       return {           template: '<div class="chart"></div>',           restrict: 'e',           replace: 'true',           scope: {               data: '='           },           link: function (scope, element, attrs) {               console.log(scope);               console.log(scope.data);           }       };});

and gets passed array controller in view.

<chart data="array"></chart>

the console output looks follows:

scope {...} $id: "006" $parent: child $root: scope ... data: array[1]     0: 10300     length: 1     __proto__: array[0] this: scope __proto__: object

and 

[]

when scope object displayed in console has 'data' attribute length 1 , entry '10300', when scope.data printed empty array '[]'.

why? confused :)

the problem array initialized in controller [] , filled through function called $watch. reason 2 console outputs seem print different states of controller. solution call function once in controller initialize array values straight away.

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.
