Populating array (by 'name') in array of arrays

Question

Lets say i have an array of arrays, of which i dont know the names, just that they are arrays, and how many of them there are.

bigArray=[smallArrayA[], smallArrayB[]]

Now i can fetch the array(s) by indexposition, like:

smallA = bigArray[0]
smallA << 'input'

But what i'd like to know is the names of the arrays, stored in the 'big' one..

bigArray.inspect

..just gives me:

[['input'],[]]

My problem is that the names of the smaller ones are going to be created dynamiclly, and i need to know their names to modify the right one, later on.

What do you mean by name? An array in ruby has only indexes, not 'names'... Maybe what you're looking for is a Hash? — Vapire

Sounds like you need a hash:

bigHash = { :a => smallArrayA, :b => smallArrayB }

Now you can refer to each element of the hash by name:

bigHash[:a]
