问题 Few queries on GKE We have few GKE CLusters running on Default VPC . Can we migrate these clusters to use SharedVPC or atleast Custom VPC ? It seems existing clusters with default VPC mode cannot be changed to SharedVPC model as per GCP documentation but can we convert to Custom VPC from default VPC How to migrate from Custom VPC to Shared VPC ? Is it creating a new Cluster from existing Cluster and select SharedVPC in networking section for new cluster and then copy the Kubernetes resources

问题 In some rare cases where this would actually be acceptable, like in unit tests, you may want to get or set the value of a private attribute, or call a private method of a type where it shouldn't be possible. Is it really impossible? If not, how can you do it? 回答1: There are two ways you can access a private method of a type, and one way to get private attributes. All require meta-programming except for the first way to invoke private methods, whose explanation still involves meta-programming

问题 I would like to call a method to give me a dict of all of the "non-private" (I use the term "private" somewhat loosely here since it does not really exist in Python) and non-builtin attributes (i.e. those that do not begin with a single or double underscore) on a class. Something like vars(MyClass) that would return only the "public" attributes on that class. I'm aware that from M import * does not import objects whose name starts with an underscore.

问题 In the class 'Tosee' below, hiddenInt is visible when I call s.hiddenInt. However, when I create a "ToSee" object in another class, 'CantSee', the private variable isn't visible. Why is this so? I was under the impression that private means that in any instance of a class, the client cant see that particular instance variable or method? Why then am I able to see hiddenInt in the main method of 'ToSee'? public class ToSee { private int hiddenInt = 5; public static void main(String[] args) {

问题 I have a question about private constructors in C++. If the constructor is private, how can I create an instance of the class? Should we have a getInstance() method inside the class? 回答1: There are a few scenarios for having private constructors: Restricting object creation for all but friend s; in this case all constructors have to be private class A { private: A () {} public: // other accessible methods friend class B; }; class B { public: A* Create_A () { return new A; } // creation rights

问题 Shouldn't it generate error when i try to set the value of a property from the extended class instead of a base class? <?php class first{ public $id = 22; private $name; protected $email; public function __construct(){ echo "Base function constructor<br />"; } public function printit(){ echo "Hello World<br />"; } public function __destruct(){ echo "Base function destructor!<br />"; } } class second extends first{ public function __construct($myName, $myEmail){ $this->name = $myName; $this-
