php - namespace error in cakephp -

-

this sample page files of app

namespace cake\controller;

use cake\controller\appcontroller;

both of these lines shows red in dreamweaver

in cakephp controllers in namespace app\controller , use app\controller\appcontroller, since appcontroller default , other controllers extend it.

namespace app\controller;  use app\controller\appcontroller;  /**  * users controller  *  * @property \app\model\table\userstable $users  */ class userscontroller extends appcontroller {      /**      * index method      *      * @return \cake\network\response|null      */     public function index()     {         $users = $this->paginate($this->users);          $this->set(compact('users'));         $this->set('_serialize', ['users']);     } }

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.
