templates

问题 I am having issues with my nested iterator class. The end() sentinel is returning 0, and I am very lost! Any help would be appreciated. I want this program to be able to take any type of input, e.g. an int, create the vector, and be able to fill the array until the end() sentinel has been reached, such as typing Q, or any non-integer. I took out a few lines of unnecessary code to shorten it. template <class T> class Set { private: vector<T> m_element; int size; public: Set() : size(0) {}; ...

问题 Chapter 16.4 Parameterized Virtuality in the C++ Templates - The Complete Guide , by David Vandevoorde and Nicolai M. Josuttis, says: C++ allows us to parameterize directly three kinds of entities through templates: types, constants ("nontypes"), and templates. However, indirectly, it also allows us to parameterize other attributes such as the virtuality of a member function. The following code was illustrated in that chapter: #include <iostream> struct NotVirtual {}; struct IsVirtual {

问题 In Woocommerce I am trying to find a solution for checking if a user is logged in on custom page and if so, redirect user to "My Account" page. Any help on this is appreciated. 回答1: Try the following, where you will replace 'some-page' by your real page ID, slug or name. The code will redirect for a defined specific page logged in users to the my account page: add_action('template_redirect', 'specific_logged_in_redirect'); function specific_logged_in_redirect() { if ( is_page('some-page') &&

问题 I have created a pdf template with 'open office writer' and filled the fields with iText. In pseudo code like this: PdfReader reader = new PdfReader("C:/temp/Template.pdf"); FileOutputStream fileOutputStream = new FileOutputStream("C:/temp/TemplateTest.pdf"); PdfStamper stamper = new PdfStamper(reader, fileOutputStream); stamper.setFormFlattening(true); stamper.getAcroFields().setField("description", "This is a important description."); stamper.close(); Now I just want the word 'important' in

问题 I am currently trying to make some email templates to be send via an Email client (SendGrid in this case). After doing some research on how to create these templates I came to the conclusion that using regular HTML & CSS is not the way to go since Mail client preprocessors (Mainly Gmail & Outlook) strip almost all styles which have been applied that are not inline. However I still am having one Issue. I can't seem to get rid of the bullet points using List-style-type: none even inline on the

问题 Sometimes I see syntax like this. template<typename T,typename = int> int foo(){ //... } what part typename = int mean? Where it can be used? 回答1: foo has two template arguments. The first is called T and the second is unnamed and defaults to int . In your piece of code alone there is no reason to use the second argument. Unnamed template arguments often come up with SFINAE. An example from cppreference: // primary template handles non-referenceable types: template<class T, class = void>

问题 For our Code Igniter application we are loading all of our javascript just before the closing body tag. so in our controllers we have $this->load->view('head', $this->head); $this->load->view('main_view_for_controller', $data); $this->load->view('foot', $this->foot); And in the foot view we have a bunch of <script src="master.js"></script> tags. These include jQuery jQuery-ui shared-functions Now this works great, until you think about JS used only on specific pages, or inline js. You can't
