The C++ containers allow script components to use things like properties which are untyped, I'd really like to also support this for the Java runtime as fits in well with the untyped dynamic nature of scripting languages. I'd looked at this before but it didn't seem so easy to do with the old M1 runtime, any objections to getting it to work with the new code? ...ant On 9/12/06, Jean-Sebastien Delfino [EMAIL PROTECTED] wrote: ant elder wrote: [snip] So the services, references and properties are untyped right? ...ant Yes -- Jean-Sebastien - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Ruby for the Java runtime? (was: Re: [C++] Beginning of a Ruby extension available)
Venkat, on IRC we were talking about how to introspect JRuby components,
after playing about with this i think you can call
getMetaClass().getMethods() on the IRubyObject rubyInstance. That gives a
map of the methods and it looks like that includeds a method name ending in
= for the attr_writer ones. For example if in your script you have
attr_writer :foo then the method map will contain a method with key foo=.

I have tried setting the java object to a ruby global variable, after

Is there any other way to do this?

Hi Venkat
I'm not sure that this helps at all but I just took a look at what Sebastien
did in C++
string expr = impl-getClass() + .new;
VALUE instance = rb_eval_string(expr.c_str());
// Get the ID of the specified method
ID method = rb_intern(operation.getName().c_str());
When it comes time to actually call the method
// Invoke the specified method
VALUE value;
if (n == 0)
{
value = rb_funcall(instance, method, 0);
}
else
{
value = rb_funcall2(instance, method, n, args);
}
So he seems to be able to deal with the class instance in C++. This is the
script he used to test with in the C++ Calculator sample.
class DivideImpl
def initialize()
print Ruby - DivideImpl.initialize\n
end
def divide(arg1, arg2)
print Ruby - DivideImpl.divide\n
arg1 / arg2
end
end
Sebastien is the man to ask really as he build the Ruby extension. He will
be able to give you the gory details no doubt when he comes on line.

Re: Ruby for the Java runtime? (was: Re: [C++] Beginning of a Ruby extension available)
After playing around with this I think what Simon and Jean-Sebastien have
already said is correct, its the .new that does it. Right now the
createInstance method is:
public RubyScriptInstance createScriptInstance() {
return new RubyScriptInstance(rubyEngine.evalScript(getScript()),
responseClasses);
}
Assuming you add a class attribute to the scdl and store that value in a
className field in RubyScript then I think the following should work:
public RubyScriptInstance createScriptInstance() {
IRubyObject rubyInstance = rubyEngine.evalScript(getScript());
if (className != null) {
rubyInstance = rubyEngine.evalScript (className + .new);
}
return new RubyScriptInstance(rubyInstance , responseClasses);
}

Re: Ruby for the Java runtime? (was: Re: [C++] Beginning of a Ruby extension available)
Sounds great. When Venkat is done with his port I would be interested in helping. Perhaps a sample demonstrating interopt between services with different language implementations. If we are using SDO for our data model how will SDO support be provided in these container extensions ? Robbie On 9/6/06, Venkata Krishnan [EMAIL PROTECTED] wrote: Hi... I am interested in taking a look at this. I hope to get a feel of implementing container extensions through this. I shall get started with this rightaway. Ant, I might need your help for this after I do some ground work.
