Ask, and ye shall recieve.
jruby 1.1.4 on JDK 1.6:
Java Code:
public interface ISayer {
public void say(String foo);
public void sayMultipleThings(String foo, String bar);
}
public class SayThings {
public static void sayThings( ISayer sayer ) {
sayer.say("Invoked from java");
sayer.sayMultipleThings("Saying Multiple", "Things From Java");
}
}
Ruby Code:
require 'java'
$CLASSPATH << '.'
class RubySayer
include Java::ISayer
def say(word)
puts "FROM RUBY: #{word}"
end
def say_multiple_things(first, second)
puts "FROM RUBY: #{first}, #{second}"
end
end
rc = RubySayer.new
Java::SayThings.say_things( rc )
When Run:
FROM RUBY: Invoked from java
FROM RUBY: Saying Multiple, Things From Java
Aside: Every time I go near java, CLASSPATH and 'one-class-per-file'
makes me want to go outside and hit something. IronRuby isn't even
finished yet and already I'd much rather use it :-)

I saw a presentation that (if I remember correctly) showed methods like doFoo becoming do_foo. So I think they mangle method names. I don't know if they do this for interface methods, which is closer to this problem.

The Java convention is that method names start with lower-case characters, so I don't imagine that there's any special handling being performed.

I know their naming convention is different, but lets see what JRuby does too.

Let's revisit that later, I'm also not sure what the details were.

When you override a virtual method you're pushing much more into CLR-world than when you're just calling some function on some method. In the latter case, you shouldn't have to know that the function you're calling is actually defined outside of Ruby, while in the former, this is a fairly important piece of information.
In any event, I recall that both John and Tomas felt that we shouldn't -- but no longer remember all the details.

Are we planning on supporting name mangling to give more Ruby-ish names? Like will we be able to do "def dispose" instead of "def Dispose"?
