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:
