Tiny bug: ParArray for ParVector on parallel collections overview

[santiagobasulto]

Under the title "Creating a Parallel Collection" (https://github.com/scala/scala.github.com/blob/master/overviews/parallel-collections/overview.md) I think this is wrong:

import scala.collection.parallel.mutable.ParArray
val pv = new ParVector[Int]

We've two options:

import scala.collection.parallel.immutable.ParVector
val pv = new ParVector[Int]

import scala.collection.parallel.immutable.ParArray
val pa = new ParArray[Int]

What do you think?

[heathermiller]

Well, no, the second one is certainly not correct. There is no ParArray in package scala.collection.parallel.immutable.

What exactly do you mean by this?

Are you saying that the two options are either ParVector or ParArray? This would also not be true, as there are several other parallel collection types.

The point of this section is to say that one can create a correction in two important ways-- the way one would normally think about creating a collection, like List(1,2,3) but for a parallel collection type instead, and then the other way is by taking an already-populated sequential collection, and converting it to a parallel collection.

I think we wrote we import a ParArray, and then in the next line we instantiate a ParVector instead.

[heathermiller]

Ah crap, yeah I didn't see that even when he brought it up here. Good grief, I'm losing it-- Ok, will fix!

[heathermiller]

Thanks Santiago!

[santiagobasulto]

Yeah, sorry, I ment

import scala.collection.parallel.mutable.ParArray

And with the two options, I was trying to figure out what were you trying to do when you wrote that.

Anyway, it's fixed now! Great!
