NAME

       Gnome2::GConf::ChangeSet -  A set of configuration changes to be made

SYNOPSIS

	   $cs = {
	       '/apps/someapp/some_int_key'    => { type => 'int',    value => 42 },
	       '/apps/someapp/some_string_key' => { type => 'string', value => 'hi' },
	   };

	   $reverse_cs = $client->reverse_change_set($cs);
	   $client->commit_change_set($cs, FALSE);

DESCRIPTION

       A "GConfChangeSet" allows you to collect a set of changes to configuration keys (set/unset operations). You can then commit all the changes
       at once.

       In C, "GConfChangeSet" is an hash containing keys and "GConfValue"s to be committed in a single pass (though not yet with an atomic
       operation).  Since perl has hashes as a built-in type, "GConfChangeSet" is threated as an hash with the GConf keys as keys, and their
       relative Gnome2::GConf::Value as payload.

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.
