Headers. It’s because templates are instantiated at compile-time, not link-time, and different translation units (roughly equivalent to your .cpp files) only “know about” each other at link-time. Headers tend to be widely “known about” at compile-time because you #include them in any translation unit that needs them. Read https://isocpp.org/wiki/faq/templates for more.
In a header file you have to include ALL the headers to make it compilable. And don’t forget to use forward declarations instead of some headers. In a source file: corresponded header file necessary project headers 3rd party libraries headers standard libraries headers system headers In that order you will not miss any of your … Read more
You can write all your function declarations first and then export them in an object: function bar() { //bar } function foo() { //foo } module.exports = { foo, bar }; There’s no magical one-liner though, you need to explicitly export the functions you want to be public.
Actually, this will send a POST request request to the server, so technically you aren’t mixing the two together : you are using POST with url parameters. There is nothing fundamentally wrong with this, as long as you don’t use your URL for parameters that should be in the form as hidden field. There are … Read more
If you just have a basic text header or footer, you can access them directly: [tableView footerViewForSection:indexPath.section].textLabel.text = [self tableView:tableView titleForFooterInSection:indexPath.section]; similarly for the header: [tableView headerViewForSection:indexPath.section].textLabel.text = [self tableView:tableView titleForHeaderInSection:indexPath.section];
Try this new source : student.h #include <iostream> struct Student { std::string lastName; std::string firstName; }; student.cpp #include “student.h” struct Student student;
The main practical difference is that if the member function definitions are in the body of the header, then of course they are compiled once for each translation unit which includes that header. When your project contains a few hundred or thousand source files, and the class in question is fairly widely used, this might … Read more
You have two header files MyClass.h and MyClass_p.h and one source file: MyClass.cpp. Lets take a look at what’s inside them: MyClass_p.h: // Header Guard Here class MyClassPrivate { public: int a; bool b; //more data members; } MyClass.h: // Header Guard Here class MyClassPrivate; class MyClass { public: MyClass(); ~MyClass(); void method1(); int method2(); … Read more
I did some additional tests and the code you posted works perfectly. If you have problems with something in how the parameters are setup, you could always to go the beforeSend call and modify the xml request yourself. $.ajaxSetup({ beforeSend: function (xhr) { xhr.setRequestHeader(“Accept”,”application/vvv.website+json;version=1″); xhr.setRequestHeader(“Authorization”,”Token token=\”FuHCLyY46\””); } });
Now with the 23.1.1 release of the design support library, you can use View header = navigationView.getHeaderView(0) TextView text = (TextView) header.findViewById(R.id.textView);
