NAME

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

SYNOPSIS

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

DESCRIPTION

       "GConfValue" is a dynamic type similar to "GValue",  and represents a value that can be
       obtained from or stored in the configuration database; it contains the value bound to a
       key, and its type.

       In perl, it's an hashref containing these keys:

       type
           The type of the data.  Fundamental types are 'string', 'int', 'float' and 'bool'.
           Lists are handled by passing an arrayref as the payload of the "value" key:

                   $client->set($key, { type => 'string', value => 'some string' });
                   $client->set($key, { type => 'float',  value => 0.5           });
                   $client->set($key, { type => 'bool',   value => FALSE         });
                   $client->set($key, { type => 'int',    value => [0..15]       });

           Pairs are handled by using the special type 'pair', and passing, in place of the
           "value" key, the "car" and the "cdr" keys, each containing an hashref representing a
           GConfValue:

                   $client->set($key, {
                                   type => 'pair',
                                   car  => { type => 'string', value => 'some string' },
                                   cdr  => { type => 'int',    value => 42            },
                           });

           This is needed since pairs might have different types; lists, instead, are of the same
           type.

       value
           The payload, containing the value of type "type".  It is used only for fundamental
           types (scalars or lists).

       car, cdr
           Special keys, that must be used only when working with the 'pair' type.
