=head1 NAME
DBIx::Class::ResultSourceHandle
=head1 DESCRIPTION
This module removes fixed link between Rows/ResultSets and the actual source
objects, which gets round the following problems
=over 4
=item *
Needing to keep C<$schema> in scope, since any objects/result_sets
will have a C<$schema> object through their source handle
=item *
Large output when using Data::Dump(er) since this class can be set to
stringify to almost nothing
=item *
Closer to being able to do a Serialize::Storable that doesn't require class-based connections
=back
=head1 METHODS
=head2 new
=cut
sub new {
my ($class, $data) = @_;
$class = ref $class if ref $class;
bless $data, $class;
}
=head2 resolve
Resolve the moniker into the actual ResultSource object
=cut
sub resolve { return $_[0]->schema->source($_[0]->source_moniker) }
=head2 STORABLE_freeze
Freezes a handle.
=cut
sub STORABLE_freeze {
my ($self, $cloning) = @_;
my $to_serialize = { %$self };
delete $to_serialize->{schema};
return (Storable::freeze($to_serialize));
}
=head2 STORABLE_thaw
Thaws frozen handle. Resets the internal schema reference to the package
variable C<$thaw_schema>. The recomened way of setting this is to use
C<$schema->thaw($ice)> which handles this for you.
=cut
sub STORABLE_thaw {
my ($self, $cloning,$ice) = @_;
%$self = %{ Storable::thaw($ice) };
$self->{schema} = $thaw_schema;
