man Gnome2::GConf::Value () - Opaque datatype for generic values
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
CWGConfValue is a dynamic type similar to CWGValue, 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 CWvalue
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 CWvalue key, the CWcar and the CWcdr 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 CWtype. 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.
