Is it possible to use "out" parameters with MacRuby, such as NSError?
In my particular case I'd like to capture errors that result from
parsing XML with NSXMLDocument using the initWithData:options:error:
method. I tried (naively) just instantiating an NSError instance and
handing it to that method, but ended up with this:
irb(main):037:0> e = NSError.new
=> #<NSError:0x80067cc40>
irb(main):038:0> doc = NSXMLDocument.alloc.initWithData(data,
options:NSXMLDocumentValidate, error:e)
ArgumentError: can't convert Ruby object `#<NSError:0x80067cc40>' to
Objective-C value of type `^@'
from (irb):38:in `initWithData:options:error:'
from (irb):38
from /usr/local/bin/macirb:12:in `<main>'
Any help or insight is appreciated.
Cheers,
Alex
