    package main;

    my $adder = My::Adder->new(fix => ['upcase(foo)']);

    # prints foo => BAR
    $adder->add({ foo => 'bar' });
    
    # prints:
    #  foo => BAR
    #  foo => BAR
    $adder->add_many([ { foo => 'bar' } , { foo => 'bar' }]);

    # prints a commit statement
    $adder->commit;

OPTIONS

autocommit

Autocommit when the exporter gets out of scope. Default 0.

METHODS

add($hash)

Receives a Perl hash and should return true or false.

commit

This method is usually called at the end of many add or add_many operations.

INHERIT

If you provide an 'add' method, then automatically your package gets a add_many method, plus a fix attribute which transforms all Perl hashes provided to the add method.
