Name

6       DBIx::Connector::Driver - Database-specific connection interface
7

Description

9       Some of the things that DBIx::Connector does are implemented
10       differently by different drivers, or the official interface provided by
11       the DBI may not be implemented for a particular driver. The driver-
12       specific code therefore is encapsulated in this separate driver class.
13
14       Most of the DBI drivers work uniformly, so in most cases the
15       implementation provided here in DBIx::Connector::Driver will work just
16       fine. It's only when something is different that a driver subclass
17       needs to be added. In such a case, the subclass's name is the same as
18       the DBI driver. For example the driver for DBD::Pg is
19       DBIx::Connector::Driver::Pg and the driver for DBD::mysql is
20       DBIx::Connector::Driver::mysql.
21
22       If you're just a user of DBIx::Connector, you can ignore the driver
23       classes.  DBIx::Connector uses them internally to do its magic, so you
24       needn't worry about them.

Interface

27       In case you need to implement a driver, here's the interface you can
28       modify.
29
30   Constructor
31       "new"
32
33         my $driver = DBIx::Connector::Driver->new( $driver );
34
35       Constructs and returns a driver object. Each driver class is
36       implemented as a singleton, so the same driver object is always
37       returned for the same driver.  The "driver" parameter should be a Perl
38       DBI driver name, such as "Pg" for DBD::Pg or "SQLite" for DBD::SQLite.
39       If a subclass has been defined for $driver, then the object will be of
40       that class.  Otherwise it will be an instance of the driver base class.
41
42   Instance Methods
43       "ping"
44
45         $driver->ping($dbh);
46
47       Calls "$dbh->ping". Override if for some reason the DBI driver doesn't
48       do it right.
49
50       "begin_work"
51
52         $driver->begin_work($dbh);
53
54       Calls "$dbh->begin_work". Override if for some reason the DBI driver
55       doesn't do it right.
56
57       "commit"
58
59         $driver->commit($dbh);
60
61       Calls "$dbh->commit". Override if for some reason the DBI driver
62       doesn't do it right.
63
64       "rollback"
65
66         $driver->rollback($dbh);
67
68       Calls "$dbh->rollback". Override if for some reason the DBI driver
69       doesn't do it right.
70
71       "savepoint"
72
73         $driver->savepoint($dbh, $name);
74
75       A no-op. Override if your database does in fact support savepoints. The
76       driver subclass should create a savepoint with the given $name. See the
77       implementations in DBIx::Connector::Driver::Pg and
78       DBIx::Connector::Driver::Oracle for examples.
79
80       "release"
81
82         $driver->release($dbh, $name);
83
84       A no-op. Override if your database does in fact support savepoints. The
85       driver subclass should release the savepoint with the given $name. See
86       the implementations in DBIx::Connector::Driver::Pg and
87       DBIx::Connector::Driver::Oracle for examples.
88
89       "rollback_to"
90
91         $driver->rollback_to($dbh, $name);
92
93       A no-op. Override if your database does in fact support savepoints. The
94       driver subclass should rollback to the savepoint with the given $name.
95       See the implementations in DBIx::Connector::Driver::Pg and
96       DBIx::Connector::Driver::Oracle for examples.
