问题 I have acquired a memory location from DirectX where my vertex information is stored. An extremely convenient way to deal with vertex information is to use a std::vector<> of a struct containing vertex info. Given that I have a pointer to a large buffer, could I use a std::vector to manage the elements in the buffer? Constructing a std::vector regularly causes it to have its own address, which isn't really what I want. Could I use operator placement new somehow? 回答1: Yes you can. Use custom

Extend Laravel 5 Response Facade

I am getting a namespacing issue when trying to extend the Response facade in Laravel 5. I have created a new folder tree under the app directory called Extensions\Facades . In this folder I have a file called AjaxResponse.php which has the following contents: <?php namespace App\Extensions\Facades; use Illuminate\Support\Facades\Response; class AjaxResponse extends Response{ public static function send($code,$body,$http_code=200){ parent::json( array( 'status'=>(string)$code, 'body' =>$body ) )->setStatusCode($http_code)->send(); exit(); } } I am registering this as a service provider in

Laravel Custom Model Methods

坚强是说给别人听的谎言 提交于 2019-12-04 07:48:29
问题 Whenever I add additional logic to Eloquent models, I end up having to make it a static method (i.e. less than ideal) in order to call it from the model's facade. I've tried searching a lot on how to do this the proper way and pretty much all results talk about creating methods that return portions of a Query Builder interface. I'm trying to figure out how to add methods that can return anything and be called using the model's facade. For example, lets say I have a model called Car and want

问题 I've been trying to figure out what the difference between app->bind and app->singleton are when setting up a service provider in Laravel. I was under the impression that if I register an singleton it would return the same instance of the object each time it was called vs bind which would be a new instance. Here is simple example: Facade: use Illuminate\Support\Facades\Facade; class DataFacade extends Facade { protected static function getFacadeAccessor() { return 'Data'; } } ServiceProvider:

Explain Facade pattern with c++ example?

I have checked with the wikipedia article , and it seems like it is missing the c++ version of a code example. I am not able to fully appreciate the Facade pattern without this, can you please help explain it to me using C++? Facade pattern: provides a unified - simplified interface to a complex subsystem or set of interfaces. It provides a higher level interface simultaneously decoupling the client from the complex subsystem. An example to help you understand .. a cab driver. You tell the cab driver 'Take me to PointX' (unified simplified high-level interface) who then begins on a sequence of
