Hello Patrick,
Thank you for the answer.
The reason, why I didn't use simple double is that the method, I want to
call, accept Number or String as parameter:
Eg.
//method 1
void x(Number n){...}
//method 2
void x(String s){...}
.. and if I call it like
$o->x(888);
the parameter 888 has been interpreted as String and I am in the wrong
wethod (method 2 instead of method 1) .
That's why I tried to create real java.lang.Double
Anyway I find your work and the idea of Inline at all great!
Thank you!
Masha

Why?
Maria,
I'll definitely look into this. I didn't do much testing with
java.lang.Number stuff since
Inline::Java should handle it automagically. So if you have a Java method
that expects
either a 'double' or a 'java.lang.Double', you should be able to pass
simply
the double in Perl
an Inline::Java will do the conversion.
Thanks,
Patrick
