Jifty::DBI::Filter::YAML(3pm) User Contributed Perl Documentation Jifty::DBI::Filter::YAML(3pm) NAME
Jifty::DBI::Filter::YAML - This filter stores arbitrary Perl via YAML SYNOPSIS
use Jifty::DBI::Record schema { column my_data => type is 'text', filters are qw/ Jifty::DBI::Filter::YAML /; }; my $thing = __PACKAGE__->new; $thing->create( my_data => { foo => 'bar', baz => [ 1, 2, 3 ] } ); my $my_data = $thing->my_data; while (my ($key, $value) = %$my_data) { # do something... } DESCRIPTION
This filter provides the ability to store arbitrary data structures into a database column using YAML. This is very similar to the Jifty::DBI::Filter::Storable filter except that the YAML format remains human-readable in the database. You can store virtually any Perl data, scalar, hash, array, or object into the database using this filter. In addition, YAML (at least the storage of scalars, hashes, and arrays) is compatible with data structures written in other languages, so you may store or read data between applications written in different languages. METHODS
encode This method is used to encode the Perl data structure into YAML formatted text. decode This method is used to decode the YAML formatted text from the database into the Perl data structure. IMPLEMENTATION
This class will attempt to use YAML::Syck if it is available and then fall back upon YAML. This has been done because the Syck library is written in C and is considerably faster. SEE ALSO
