FUNCTIONS
- all_defined
-
$bool = all_defined( @values )Return FALSE if some of values in array are undefined
- hf (hash filter)
-
@values_by_filtered_keys = hf( $precompiled_regex, %hash_array ) %hash_array_of_filtered_keys = %{hf( $precompiled_regex, %hash_array )}EXAMPLE:
%hash = (key_ax=>'val_ax', key_ay=>'val_ay', key_bx=>'val_bx', key_by=>'val_by'); @values = hf(qr/\w+/,%hash); %values = %{hf(qr/\w+/,%hash)}; - set_hmv
-
set_hmv( \%hash, $key, $val, [ $force_single ] );set hash multi-value - for multiple appearances of same key are values stored as arrayref rather than direct value. Usefull when parsing cooikes or url with multiple param names.
$force_single set to 1 drops/replaces previously stored values with the $val for the $key specified.
SEE ALSO get_hmv
- get_hmv
-
get_hmv( \%hash, $key, [ $index ] );get hash multi-value - counterpart for set_hmv.
TIP: use $index = -1 to get last value or other negative values to index from end of values array. (Same way as with common perl array)
