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.
