Sets or gets the storage backend. Defaults to L<DBIx::Class::Storage::DBI>.

=head2 class_resolver
****DEPRECATED****
L<DBIx::Class::ClassResolver::Passthrough>, which returns whatever you give
it. See resolve_class below.

__PACKAGE__->mk_classdata('class_resolver' =>

+=begin hidden
+
=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.
+=end hidden
+
=cut

$class->schema_instance->connection(@info);

+=begin hidden
+
=head2 setup_schema_instance
Creates a class method ->schema_instance which contains a DBIx::Class::Schema;
call ->setup_schema_instance in order for subclasses to find the schema and
register themselves with it.
+=end hidden
+
=cut
sub setup_schema_instance {

=head2 txn_begin
Begins a transaction (does nothing if AutoCommit is off).
+=end hidden
+
=cut
sub txn_begin { shift->schema_instance->txn_begin(@_); }
+=begin hidden
+
=head2 txn_commit
Commits the current transaction.

=head2 txn_rollback
Rolls back the current transaction.

+=begin hidden

=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.

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.
