NAME
MooseX::Storage::Deferred - A role for undecisive programmers
SYNOPSIS
package Point;
use Moose;
use MooseX::Storage;
our $VERSION = '0.01';
with 'MooseX::Storage::Deferred';
has 'x' => (is => 'rw', isa => 'Int');
has 'y' => (is => 'rw', isa => 'Int');
1;
my $p = Point->new(x => 10, y => 10);
## methods to freeze/thaw into
## a specified serialization format
## (in this case JSON)
# pack the class into a JSON string
$p->freeze({ format => 'JSON' }); # { "__CLASS__" : "Point", "x" : 10, "y" : 10 }
# pack the class into a JSON string using parameterized JSONpm role
$p->freeze({ format => [ JSONpm => { json_opts => { pretty => 1 } } ] });
# unpack the JSON string into a class
my $p2 = Point->thaw(
'{ "__CLASS__" : "Point", "x" : 10, "y" : 10 }',
{ format => 'JSON' }
);DESCRIPTION
This role is designed for those times when you need to serialize into many different formats or I/O options.
It basically allows you to choose the format and IO options only when you actually use them (see the SYNOPSIS for more info)
SUPPORTED FORMATS
- JSON
- JSONpm
- YAML
- Storable
SUPPORTED I/O
- File
- AtomicFile
NOTE: The StorableFile I/O option is not supported, this is because it does not mix well with options who also have a thaw and freeze methods like this. It is possible to probably work around this issue, but I don't currently have the need for it. If you need this supported, talk to me and I will see what I can do.
METHODS
- freeze ($type_desc)
- thaw ($data, $type_desc)
- load ($filename, $type_desc)
- store ($filename, $type_desc)
Introspection
- meta
