NAME

6       Gnome2::GConf::Value -  Opaque datatype for generic values
7

SYNOPSIS

9         $client = Gnome2::GConf::Client->get_default;
10         $client->set($config_key,
11             {
12               type  => 'string',
13               value => 'Hello, World',
14             });
15         print "The Meaning of Life." if ($client->get($another_key)->{value} == 42);
16

DESCRIPTION

18       "GConfValue" is a dynamic type similar to "GValue",  and represents a
19       value that can be obtained from or stored in the configuration
20       database; it contains the value bound to a key, and its type.
21
22       In perl, it's an hashref containing these keys:
23
24       type
25           The type of the data.  Fundamental types are 'string', 'int',
26           'float' and 'bool'.  Lists are handled by passing an arrayref as
27           the payload of the "value" key:
28
29                   $client->set($key, { type => 'string', value => 'some string' });
30                   $client->set($key, { type => 'float',  value => 0.5           });
31                   $client->set($key, { type => 'bool',   value => FALSE         });
32                   $client->set($key, { type => 'int',    value => [0..15]       });
33
34           Pairs are handled by using the special type 'pair', and passing, in
35           place of the "value" key, the "car" and the "cdr" keys, each
36           containing an hashref representing a GConfValue:
37
38                   $client->set($key, {
39                                   type => 'pair',
40                                   car  => { type => 'string', value => 'some string' },
41                                   cdr  => { type => 'int',    value => 42            },
42                           });
43
44           This is needed since pairs might have different types; lists,
45           instead, are of the same type.
46
47       value
48           The payload, containing the value of type "type".  It is used only
49           for fundamental types (scalars or lists).
50
51       car, cdr
52           Special keys, that must be used only when working with the 'pair'
53           type.
