=head1 NAME
DBIx::Class::DB - (DEPRECATED) classdata schema component
=head1 DESCRIPTION
This class is designed to support the Class::DBI connection-as-classdata style
for DBIx::Class. You are *strongly* recommended to use a DBIx::Class::Schema
instead; DBIx::Class::DB will not undergo new development and will be moved
to being a CDBICompat-only component before 1.0. In order to discourage further
use, documentation has been removed as of 0.08000
=begin HIDE_BECAUSE_THIS_CLASS_IS_DEPRECATED
=head1 METHODS
=head2 storage
Sets or gets the storage backend. Defaults to L<DBIx::Class::Storage::DBI>.
=head2 class_resolver
****DEPRECATED****
Sets or gets the class to use for resolving a class. Defaults to
L<DBIx::Class::ClassResolver::Passthrough>, which returns whatever you give
it. See resolve_class below.
=cut
__PACKAGE__->mk_classdata('class_resolver' =>
'DBIx::Class::ClassResolver::PassThrough');
=head2 connection
__PACKAGE__->connection($dsn, $user, $pass, $attrs);
Specifies the arguments that will be passed to DBI->connect(...) to
instantiate the class dbh when required.
=cut
sub connection {
my ($class, @info) = @_;
$class->setup_schema_instance unless $class->can('schema_instance');
$class->schema_instance->connection(@info);
}
=head2 setup_schema_instance
Creates a class method ->schema_instance which contains a DBIx::Class::Schema;
all class-method operations are proxies through to this object. If you don't
call ->connection in your DBIx::Class::DB subclass at load time you *must*
call ->setup_schema_instance in order for subclasses to find the schema and
register themselves with it.
=cut
sub setup_schema_instance {
my $class = shift;
my $schema = {};
bless $schema, 'DBIx::Class::Schema';
$class->mk_classdata('schema_instance' => $schema);
}
=head2 txn_begin
Begins a transaction (does nothing if AutoCommit is off).
=cut
sub txn_begin { shift->schema_instance->txn_begin(@_); }
=head2 txn_commit
Commits the current transaction.
=cut
sub txn_commit { shift->schema_instance->txn_commit(@_); }
=head2 txn_rollback
Rolls back the current transaction.
=cut
sub txn_rollback { shift->schema_instance->txn_rollback(@_); }
=head2 txn_do
Executes a block of code transactionally. If this code reference
throws an exception, the transaction is rolled back and the exception
is rethrown. See L<DBIx::Class::Schema/"txn_do"> for more details.
=cut
sub txn_do { shift->schema_instance->txn_do(@_); }

sub resolve_class {

}
}
=head2 resultset_instance
Returns an instance of a resultset for this class - effectively
mapping the L<Class::DBI> connection-as-classdata paradigm into the
native L<DBIx::Class::ResultSet> system.
=cut
sub resultset_instance {
$_[0]->result_source_instance->resultset
}
=head2 result_source_instance
Returns an instance of the result source for this class
=cut

# Yep. this is horrific. Basically what's happening here is that
# (with good reason) DBIx::Class::Schema copies the result source for
# registration. Because we have a retarded setup order forced on us we need
# to actually make our ->result_source_instance -be- the source used, and we
# need to get the source name and schema into ourselves. So this makes it
# happen.
