MooseX::Storage::Deferred - A role for indecisive programmers

version 0.52

  package Point;
  use Moose;
  use MooseX::Storage;
  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' }
  );

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)

JSON
JSONpm
YAML
Storable

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.

freeze ($type_desc)
thaw ($data, $type_desc)
load ($filename, $type_desc)
store ($filename, $type_desc)
