How to enumeratorize in 1.6.7 // when will enumeratorize be made public?
It looks like in master, RubyEnumerator.enumeratorize() is public, but as
of 1.6.7 it is not. I'm wondering what the idiomatic way is to do this? In
1.6.6 I used "RubyEnumerator.RubyEnumeratorKernerl.obj_to_enum", but that
is no longer working.
As always, I appreciate the help. Writing jruby libraries in Java is a
brave new world.
My method is the following:
@JRubyMethod
public IRubyObject each(ThreadContext context, Block block) throws
ExecException {
//TODO would like to return an Enumerator, but the necessary
methods are taken?
if (!block.isGiven()) return
RubyEnumerator.RubyEnumeratorKernel.obj_to_enum(context, this);
getIterator(context).each(context,block);
return this;
/* In a future release of JRuby when enumeratorize is made public
(which is planned), should replace the above with the below
if (!block.isGiven()) return
RubyEnumerator.enumeratorize(context.getRuntime(), this, "each");
*/
}
and the error is below:
Java::JavaLang::NoSuchMethodError:

Re: How to enumeratorize in 1.6.7 // when will enumeratorize be made public?
Posted by Jonathan Coveney <jc...@gmail.com>.
I sent this to the wrong list serv :) Meant to send it to the JRuby list
