Re: Data Structure: HOA or AOH ??

@table{@cols} = split /\t/;
[download]

The input data is stored in a ~~array of hash~~ hash slice with each element in the @cols as keys. The reference to the hash table is then stored in @data.

free download Chapter 2 has a figure explaining just this!

Update: @table{@cols} = split /\t/; is a hash slice as others have mentioned!

ikegami, Thanks for pointing out the mistake. I am still trying to wrap my brain around a hash slice.	[reply]

It's just like `$hash{foo}`, except you have multiple keys. `@hash{qw( foo bar )} = (1, 2);` [download] is basically the same as `$hash{foo} = 1; $hash{bar} = 2;` [download] (I said "basically" because there is a difference. The former uses a list assignment while the latter uses two scalar assignments. List assignments don't return the same as scalar assignments. See Mini-Tutorial: Scalar vs List Assignment Operator)	[reply] [d/l] [select]
