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.
