This class file could be generated by the javabind library, but I thought it would be overkill for what I needed and might actually make the loading time longer, since it would have to be generated.
You don't have to generate it at (java) runtime.
Do you mean what I already do: generate it by writing java code and compiling. Or at compile-time? Or something else?
I mean that you can build the generation of the Java code into the capabilities of your binding library. Doesn't the C++ binding description contain all the information you need to generate the Java code? If so, you could generate it from C++,
Yes it does, and yes I can. But generating from C++ might be costly at initialization-time if I had to do it for hundreds of methods, which is the case for me. I will give this a try next week and see if it really performs wells. If you know how to create a contiguous buffer composed with data from c-style strings strictly at compile-time without constexpr that surely would solve any problems I could have with initialization time. You may know how from this code: register_class<my_class>("MyClass") [ function("Foo", &my_class::foo) , function("Bar", &my_class::bar) ]; I can create a contiguous buffer of size N with these strings without copying at runtime? It is easy to learn the sizes at compile-time, which eliminates strlen calls and I can at least allocate the buffer at compile-time, but I really don't know how to avoid copying. Or the compiler just optimizes these copies away at compile-time?
