abstract class for objects that has filters
my $record = Jifty::DBI::Record->new(...);
my @filters = $record->output_filters;
This abstract class provide generic interface for setting and getting
input and output data filters for Jifty::DBI objects.
You shouldn't use it directly, but Jifty::DBI::Handle, Jifty::DBI::Record
and Jifty::DBI::Column classes inherit this interface.
Returns array of the input filters, if arguments list is not empty
then set input filter.
Deals similar with list of output filters, but unless
you defined own list returns reversed list of the input
filters. In common situation you don't need to define
own list of output filters, but use this method to get
default list based on the input list.
Sets the input and output filters at the same time. Returns a hash,
with keys "input" and "output", whose values are array references to
the respective lists.
