*fine
<yorickpeterse>
You mean pass the data to process in the constructor?
<apeiros>
AlecTaylor: if you want multiple constructors, have a normalized new, and just define the other constructors as class methods which normalize the input and call new
<AlecTaylor>
Mmm
<apeiros>
if that's not feasible, you probably shouldn't stick it into one class
gianlucadv has joined #ruby-lang
gianlucadv has quit [Remote host closed the connection]
<apeiros>
yorickpeterse: IMO a different constructor can have side-effects. but only on the created object. e.g. it runs a couple of methods for you already (your socket example would probably fit that bill)
<yorickpeterse>
apeiros: what I mostly meant is that some object shouldn't start batch-processing lord knows how much data when you create an instance of it
<yorickpeterse>
It also introduces this pattern where you create instances you never use
<yorickpeterse>
e.g.
<yorickpeterse>
MyFoobarObject.new(...) # that's all, no methods are ever called on it since it already did everything
<apeiros>
ah. yes, true
<yorickpeterse>
which is basically procedural programming using objects
<yorickpeterse>
aka Javascript
* yorickpeterse
runs
<apeiros>
what I mean is that with your example `MyFoobarBatch.new(rows_here).process`, one could make a constructor `MyFoobarBatch.process(rows_here)` which does precisely that: call new(rows_here).process.
<yorickpeterse>
Oh right

Yeah that's fine, just don't overwrite "new"

<agrinb>
that makes perfect sense, and I honestly haven't looked for alternatives because I want to understand what's happening with the pop method.
JohnFord has joined #ruby-lang
<wallerdev>
i think everytime the block runs arr.each checks that its not past the end of the array
<wallerdev>
so at 1, it removes the 7, sees theres 6 items in the list and keeps going, 2 removes 6, 5 items, 3 removes 5, 4 items, 4 removes 4, 3 items in the array now, it sees its trying to iterate past the end and stops
<wallerdev>
somethin like that
<wallerdev>
not sure about the internals of it
<wallerdev>
but a lot of languages dont let you even modify arrays in foreach loops because of the weird issues that can happen
<aledovsky>
It leaves precisely half of array unprocessed, so your theory seems valid
<agrinb>
ok, that makes sense, will try the alternative you suggested. Thanks
