Variadic template inheritance order and syntax

QUESTION

Variadic template inheritance order and syntax

Asked 2021-Mar-04 at 10:21

I am trying to implement a signal/slot system via templates to get into some advanced usage of templates. I looked up existing implementations and found one at https://github.com/skypjack/eventpp. I have been trying to understand how it works and pretty much figured it out but there are still some things I can't wrap my head around and couldn't find anything on the internet (didn't know what to search for).

Following is an executable minimal example of the code I took from the github repo plus additional code I implemented myself:

Why is this template instantiated first? I would have expected it to be last (before Bus).

constructor call and instantiation are different thing

Bus inherits from BusBase<2, KeyPressedEvent, KeyReleasedEvent> which inherits from BusBase<2, KeyReleasedEvent> which inherits from BusBase<2>

Call order is from (grand-)parents, members, constructor block, so the outputs you have.

Why are the parameters both in the template declarations and in the struct declarations?

That is the syntax for partial template specialization.

As a note partial specialization is unneeded here and can be rewritten as:

Vulnerabilities

No vulnerabilities reported

Install eventpp

The library itself is header only and doesn't need building. There are three parts of code to test the library,. All parts are in the tests folder. All three parts require CMake to build, and there is a makefile to ease the building. Go to folder tests/build, then run make with different target.
unittests: tests the library. They require C++17 since it uses generic lambda and std::any (the library itself only requires C++11).
tutorials: sample code to demonstrate how to use the library. They require C++11. If you want to have a quick study on how to use the library, you can look at the tutorials.
benchmarks: measure the library performance.
make vc19 #generate solution files for Microsoft Visual Studio 2019, then open eventpptest.sln in folder project_vc19
make vc17 #generate solution files for Microsoft Visual Studio 2017, then open eventpptest.sln in folder project_vc17
make vc15 #generate solution files for Microsoft Visual Studio 2015, then open eventpptest.sln in folder project_vc15
make mingw #build using MinGW
make linux #build on Linux
make mingw_coverage #build using MinGW and generate code coverage report

Support

Tested with MSVC 2019, MinGW (Msys) GCC 7.2, Ubuntu GCC 5.4, and MacOS GCC. GCC 4.8.3 can compile the library, but we don't support GCC prior to GCC 5. In brief, MSVC, GCC, Clang that has well support for C++11, or released after 2019, should be able to compile the library.
