kandi X-RAY | HandleWrapper Summary

HandleWrapper is a Java library typically used in Programming Style, Bytecode, Minecraft applications. HandleWrapper has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

MethodHandles can be as fast as direct invocation, as long as they are static final fields. Then they can be inlined. But what if we want to use them dynamically? I wanted to learn a thing or 2 about bytecode, so here I use ASM to create classes at runtime that contain the MethodHandle as a static final field. These "HandleWrappers" are almost as fast as direct invocation.

Use a queue. If you encounter a folder, push it to the queue. When all children in the current directory are done, then pull from the queue and dive in and repeat, more like a modified BFS.

Asked 2019-Aug-22 at 14:03

I want to simplify a code by using a constexpr function instead of multi constexpr if branches.

This is the code with the old code commented the old code compiles with msvc (vs 2017 with c++17) and clang (android ndk r20), but it fails to compile with clang 8 in for windows x64 in visual studio !

and the new code neither compiles with msvc nor clang

Make sure you have the correct "C++ Language Standard" set in the property pages for your project. The default for VS 2017 is C++14.

Right click on your project and select "Properties". Then expand the C/C++ node on the tree view on the left hand side. Select "Language" from the expanded menu options. Check that the "C++ Language Standard" is set to ISO C++17 Standard (/std:c++17).

If its blank, it will default to C++14.

QUESTION

Is it possible to treat a pointer as an integral type in non-type template parameters?

Asked 2018-Mar-03 at 02:12

I'm trying to create a template where a default value can be passed as a non-type parameter.

The original type (WINAPI's HANDLE) is a pointer type from the compiler perspective, but otherwise is treated as an integral type from a user perspective.

In my code, I have a templated handle wrapper class that I use, but I take a different approach with it than you are with yours. I define a separate traits class for each type of handle to be wrapped, and then use a template parameter to specify which traits to use in the wrapper.

Try doing something similar in your case, eg:

Yes, there is: You would have to implement a conversion operator, i.e. operator HANDLE(), that returns the stored handle.^*

Nothing I'd recommend. There's enough invisible code in C++ already. No need to add to it, less so when there is so little to be had.

^* Incidentally, the code you linked to already implements the appropriate conversion operator, operator traits::HandleType(). In other words: You don't need to implement anything in particular to use your favored syntax.
