NAME

Data::PowerSet::Hash - Power sets of hashes

VERSION

version 0.04

DESCRIPTION

This provides you with a power set (basically all combinational iterations) for your hashes. This only does it for hashes, if you want them done for arrays, I suggest using Data::PowerSet. Please view the SEE ALSO section below.

SUBROUTINES/METHODS

hash_powerset

Create a powerset from hash keys.

use Data::PowerSet::Hash 'hash_powerset';

my @pset = hash_powerset(
    husband => 'Homer Simpson',
    wife    => 'Marge Simpson',
);

# @pset = (
#     {
#         husband => 'Homer Simpson',
#         wife    => 'Marge Simpson',
#     },
#     { husband => 'Homer Simpson' },
#     { wife    => 'Marge Simpson' },
#     {},
# )

EXPORT

hash_powerset(%hash)

See documentation for it above.

SEE ALSO

For arrays, you should check out Data::PowerSet or List::PowerSet.
