NAME

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

VERSION

version 0.03

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.

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