Jifty::DBI::HasFilters - 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.
