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.

YAML::Any - Pick a YAML implementation and use it.
SYNOPSIS
use YAML::Any;
$YAML::Indent = 3;
my $yaml = Dump(@objects);
DESCRIPTION
There are several YAML implementations that support the Dump/Load API. This module selects the best one available and uses it.
ORDER
Currently, YAML::Any will choose the first one of these YAML implementations that is installed on your system:
YAML::XS
YAML::Syck
YAML::Old
YAML
YAML::Tiny
OPTIONS
If you specify an option like:
$YAML::Indent = 4;
And YAML::Any is using YAML::XS, it will use the proper variable: $YAML::XS::Indent.
SUBROUTINES
Like all the YAML modules that YAML::Any uses, the following subroutines are exported by default:
Dump
Load
and the following subroutines are exportable by request:
DumpFile
LoadFile
METHODS
YAML::Any provides the following class methods.
YAML::Any->order;
This method returns a list of the current possible implementations that YAML::Any will search for.
YAML::Any->implementation;
This method returns the implementation the YAML::Any will use. This result is obtained by finding the first member of YAML::Any->order
that is either already loaded in %INC or that can be loaded using "require". If no implementation is found, an error will be thrown.
