Ruby Programming Language :: get info from object


	get info from object_id Hi All, apologies in advance if this is so stupid for you (my feeble mind is working feebly :) so here goes, Given an object_id, how do i get back the object that id stands for? i'm looking for something like, a=[1,2,3] x=a.object_id b=Object.id_to_object(x) #-> returns object pointed by a wc [1,2,3] b.class #-> returns Array b #-> [1,2,3] b == a #-> true thank you and kind regards -botp Pea wrote: > Given an object_id, how do i get back the object that id stands for? ObjectSpace._id2ref is what you're looking for. -- vjoel : Joel VanderWerf : path berkeley edu : 510 665 3407 From: Joel VanderWerf [mailto:v@path.berkeley.edu] : # > Given an object_id, how do i get back the object that id stands for? # # ObjectSpace._id2ref is what you're looking for. yikes! objectspace is the key word. should have done qri object -Osa in the first place. arrghhh.. many thanks again, Joel. kind regards -botp Pea wrote: > yikes! objectspace is the key word. should have done qri object -Osa in the first place. arrghhh.. Thanks for reminding me about qri. What does the "s" do? I see "a", but not "s" in the help for -O: -O, --order ORDER Specify lookup order.

I used -S for full text, so that should be qri object -SOa I usually pipe it then to less, since it's full text search output, qri object -SOa \| less On this current case, i should have taken a quick peek first by piping it to grep like eg, C:\family\ruby>qri object -SOa \| less \| grep -i object_id .. r = ObjectSpace._id2ref(s.object_id) #=> 'I am a string' .. ethod: object_id .. Document-method: object_id and no two active objects will share an id. Object#object_id is a share an id. Object#object_id is a different concept from the :name Found in system Object#object_id objects will share an id. Object#object_id is a different concept and no two active objects will share an id. Object#object_id is a share an id. Object#object_id is a different concept from the :name .. Soon-to-be deprecated version of Object#object_id. .. p res.body.object_id # 538149362 .. p res.read_body.object_id # 538149362 There, first hit hints at id2ref.. btw, this is qri, wc is the slower brother of the faster fri; but then qri is a lot faster than the original ri, but you were much faster :), so.. thanks and kind regards -botp
