unique data

Peter Meier

9/24/2006 12:24:00 PM

Hi,

I'd like to use the gem "rubytree" to store some data in a tree.
But this requires a unique name for each node.

Does anybody has some advice, how to generate such a unique id?
Could be a random, but unique number, ...

Thanks
Peter

Hi Peter,

How about a type-4 UUID?

class UUID
@@range = %{0123456789abcdef}.split(//)
@@indices = [7,11,15,19]
def self.new
uuid=[]
32.times { |i|
uuid << @@range[rand(16)]
uuid << '-' if @@indices.include?(i)
}
uuid.join
end
end
puts UUID.new

Mabye just using the object_id of the node itself or the object you're
inserting into the node would work?

Regards,
Jordan

Why not use a counter?

Doh! Curse you rubyists for always thinking of easy ways to do things!
I'm going to fire up perl5 and write some code, just to spite you! ;)

AleXX

does this mean our CHINESE in Malaysia can take over
Malaysia in this century ?

just like all of OUR Chinese People in Malaysia are
demanding for racial EQUALITY in Malaysia with the Malays .?

If Malays allow every one to be EQUAL in Malaysia ,
that means our CHINESE PEOPLE in Malaysia can take over
Malaysia , if
Chinese are Equal to the Malays in Malaysia , if this is
going to be a Chinese century ?


You get What I mean , AleXX ?

Hey Dik Likker Komin, you've repeatedly said, "I hate Chinese, that's
why I'm gay." You're a bloody illogical hypocrite.

Time to get lost to downtown Cambodia, where the boys are waiting to
give your backside a good polish so that it'll glow in the drak.
Remember to wear your sister's panties for the audition and don't
steal the used condoms.
