Asp Forum - enumeration with symbol name information

Hello everybody...
I have a beginne's question:

I've created class for my numeric constants, it looks like:

class MyClass

NAME1 = 0
NAME2 = 1
NAME3 = 2
#etc...

def self.to_s(something)
case something
when 0
"NAME1"
when 1
"NAME2"
when 2
"NAME3"
#etc...
end
end

end

What is more elegant way to do this? Basically, I want to convert the
numerical value to string representation (ideally via identifier name).

Thanks in advance,
Sasa

If your numeric values always start from 0, then you may use an array:

class MyClass
NAMES = [ 'NAME1','NAME2','NAME3' ]

def self.to_s(something) # personally I would rather avoid redefining class.to_s
NAMES[something.to_i] || default_value
end
end

If this is unacceptable, you may use a hash:

NAMES = { 1 => 'NAME1', 2 => 'NAME2', 5 => 'NAME3' }
NUMBERS = Hash[ *NAMES.map {|k,v| [v,k]}.flatten ] # may be useful :-)

def self.to_s(something)
NAMES[ something ] || defaul_value
end

def self.to_i(something) # may be useful :-)
NUMBERS[ something ] || default_number
end

Hmm. Really? I didn't think the preview spoiled anything.

Oh it's bad. I may need to go into full snark mode on this one.

We now know she lives (yeah not a surprise) and apparently Lena really
thinks Annie is a traitor. I originally thought Lena and Annie were
plotting together (perhaps they still are).

I didn't think the preview spoiled anything.

Perhaps not spoiled but it narrowed down the speculation. At the end of
a Batman cliffhanger, I don't want a preview for next week showing that
he escaped the trap.

The sad thing is, unlike The Mindy Project, I'm actually going to watch
this turkey every week. :-( If only I had the willpower not to.

Okay, it proved that she wasn't wearing the vest from earlier (if she
had been, I'd have quit watching on the spot)

and apparently Lena really

Oh. Interesting. I assumed Lena was really the traitor.

Now that they show the episodes back to back, you don't have to wait! :D

Maybe Lena is a baddie inside the CIA and killed the Russian spy and shot
Annie to cover up what might be found with further investigation. There's no
way Arthur would have approved wet work on her without hearing her side.
Maybe she was just jealous of Annie. The shooting points to Lena being a
baddie imho unless this is a total fakeout. "Nina" (Lena) has a history of
being bad and a traitor. :)

It never occurred to me that she was a traitor. But that does seem like
a very plausible explanation.

Jealously really doesn't rise to the level of murder under the
circumstances. Plus she didn't have anything to be jealous about.

The shooting
> points to Lena being a baddie imho unless this is a total fakeout.

That's what I was suspecting *before* the shooting. But I don't see the
point in shooting *both* of them. Shooting one, sure, but not both. I
just don't see the angle in that.

Then again some of the actions simply don't make sense to me. I
remember being particular annoyed at the mall scene when they parked the
undercover van right in front of the entrance then Annie emerged from
it. I was thinking shouldn't she have a cover story for how she got
there and how she's going to get back. And what if he parked his car
right next to theirs (they were parked in the front after all) and saw
her exit the vehicle.

Nothing wrong with that, lots of people hate-watch shows just to snark
about it later.

Fortunately for me, I'm dumb enough not to care that planes fall out
from the sky, so I'll still be entertained by it. I'm mostly just
bummed that I won't get to see more Elizabeth Mitchell.

Have seen all that, but not the preview.

Jai may no longer be in the show, but the writers are
certainly milking his previous involvement for all its
worth.
