Hi there,
I've got a hash that has keys which contain either
- array references
- scalar values
for example:
@values = (12398712984, 19286192879);
$hashofarrays{'family'}{'arrayref'} = \@values;
$hashofarrays{'family'}{'scalar'} = 12938712938;
I'm trying to map the hash into another array that would just be a flattened
list of values. (a combination of the scalar values and the individual array
values)
I'm iterating through each key in the hash and then using 'map' on the key
to do this at the moment.
I can get it to work for all the array references by mapping on the
de-referenced array ref, like this:
map { push @items, $_ } ( @{$hashofarrays{'family'}{'arrayref'} }
);
But that ignores all the scalar values...it only gets the keys that contain
array references.
To get the scalars, the following works:
map { push @items, $_ } ( $hashofarrays{'family'}{'scalar'} );
Is there an elegant / idiomatic way to do both at once?
I'm guess I could do it using a conditional that checks the hash value and
executes one of the above statements as I iterate through the hash keys, but
if theres a better way...
Any ideas? Your time is appreciated!
Thanks
Mike
