 |
|
Is it possible to steal the Java API?
At the lowest level, everything in the Java API is already implemented as
calls to the underlying native OS. And the myriad of classes built on top of
these low-level calls could be automatically ported to C++ using an expert
system of rules. And even if you don't go that route, you can use gcc to
compile into a native library, which you could presumably link to C++ object
code.
Can or has someone done this and packaged it as a C++ library fully compatible
with the Java API that comes with a J2SE runtime environment?
I'm not thinking of a manual port by hand. I'm talking automation. Every
time a new JDK comes out, you rebuild and poof! you have a new C++ library.

I'm not convinced it would be as easy as you make it and even if it
was, I see no point in doing it. The Java library is obviously written
with Java in mind, that is it makes the most of Java specific features
by doing things the Java way. This is not necessarily the best way to
do things in C++, though.
You may argue that it wouldn't be that important how the library did
things internally as long as its functionality was available to C++
code. However even the library interface is Java oriented. Consider
for instance the difference between Java collection classes and the
STL containers and in general the importance generic programming has
acquired over inheritance based genericity in the C++ community.
Porting the Java library to C++ would impose a programming style that
many would consider less than perfect.
