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.
