How to use polymorphism or inheritance in static classes?

空扰寡人 提交于 2021-01-27 14:01:39
问题 Look, I know static classes can't inherit or implement. The question is "what the heck is the right C# + OOP pattern to implement this?". "This" is described below: I want to define a common set of both definition and implementation for a group of classes where all but one type should be static. Namely, I want to make some arbitrary base converters where each have exactly the same four members: // Theoritical; static classes can't actually implement interface IBaseConverter { int Base { get;

Xcode 9: Linking a static framework against another static framework

问题 In the spirit of Xcode 9's "revolutionary" feature, namely compiling static frameworks, we are trying to make our subprojects build as static frameworks, so they can be linked statically against the main application target. One of our sub-projects has a static framework dependency itself (Firebase). When we build the sub-project as a dynamic framework, everything works fine, but once we switch it to mach-o staticlib, suddenly, it loses the Firebase library symbols. Here is the output of nm

Netlify Redirect not working

夙愿已清 提交于 2021-01-27 07:20:24
问题 so yesterday I was having a problem because I wasn't able to implement a 301 redirect to my page hosted on the GitHub pages. Today I found Netlify which should be able to do 301 redirects. However something is not working, the docs say I need to add the redirect in a _redirect file, but nothings working. Any ideas what I am doing wrong? Here is the Test page: https://peaceful-swanson-2960b1.netlify.com/ (It should redirect to news when you click on blog) Here is the GitHub Repo: https:/

valgrind --trace-children=yes reports leak despite atexit cleanup

心已入冬 提交于 2021-01-27 06:09:26
问题 I'm trying to avoid false positives with valgrind, but I'm suck with a combination of atexit() and fork() , despite using --trace-children=yes . My code: #include <stdio.h> #include <unistd.h> #include <stdlib.h> static int * arr; static void cleanup() { free(arr); printf("free arr as: %p\n", (void *)arr); } int main() { arr = malloc(16 * sizeof(int)); printf("allocated arr as: %p\n", (void *)arr); atexit(cleanup); pid_t pid = fork(); if (pid == -1) { exit(1); } else if (pid == 0) { // child

C++ Get class type inside static function

喜欢而已 提交于 2021-01-27 04:41:06
问题 Inside of a static member function I need to get the type. class MyClass { public: static void myStaticFunc(); ... }; And then in the implementation I want to have: void MyClass::myStaticFunc() { // Get MyClass as a type so I can cast using it (get_type_from_static_function()*)someOtherVariable; } Is this even possible? Normally I would use something from typeinfo on an object but I don't have this to work with. I do not want to just use (MyClass*) because this is going inside of a macro and

How to load static files on heroku server?
