NAME

6       Net::DBus::RemoteObject - Access objects provided on the bus
7

SYNOPSIS

9         my $service = $bus->get_service("org.freedesktop.DBus");
10         my $object = $service->get_object("/org/freedesktop/DBus");
11
12         print "Names on the bus {\n";
13         foreach my $name (sort @{$object->ListNames}) {
14             print "  ", $name, "\n";
15         }
16         print "}\n";

DESCRIPTION

19       This module provides the API for accessing remote objects available on
20       the bus. It uses the autoloader to fake the presence of methods based
21       on the API of the remote object. There is also support for setting
22       callbacks against signals, and accessing properties of the object.
23

METHODS

25       my $object = Net::DBus::RemoteObject->new($service, $object_path[,
26       $interface]);
27           Creates a new handle to a remote object. The $service parameter is
28           an instance of the Net::DBus::RemoteService method, and
29           $object_path is the identifier of an object exported by this
30           service, for example "/org/freedesktop/DBus". For remote objects
31           which implement more than one interface it is possible to specify
32           an optional name of an interface as the third parameter. This is
33           only really required, however, if two interfaces in the object
34           provide methods with the same name, since introspection data can be
35           used to automatically resolve the correct interface to call cases
36           where method names are unique. Rather than using this constructor
37           directly, it is preferrable to use the "get_object" method on
38           Net::DBus::RemoteService, since this caches handles to remote
39           objects, eliminating unneccessary introspection data lookups.
40
41       my $object = $object->as_interface($interface);
42           Casts the object to a specific interface, returning a new instance
43           of the Net::DBus::RemoteObject specialized to the desired
44           interface. It is only neccessary to cast objects to a specific
45           interface, if two interfaces export methods or signals with the
46           same name, or the remote object does not support introspection.
47
48       my $service = $object->get_service
49           Retrieves a handle for the remote service on which this object is
50           attached. The returned object is an instance of
51           Net::DBus::RemoteService
52
53       my $path = $object->get_object_path
54           Retrieves the unique path identifier for this object within the
55           service.
56
57       my $object = $object->get_child_object($subpath, [$interface])
58           Retrieves a handle to a child of this object, identified by the
59           relative path $subpath. The returned object is an instance of
60           "Net::DBus::RemoteObject". The optional $interface parameter can be
61           used to immediately cast the object to a specific type.
62
63       $object->connect_to_signal($name, $coderef);
64           Connects a callback to a signal emitted by the object. The $name
65           parameter is the name of the signal within the object, and $coderef
66           is a reference to an anonymous subroutine. When the signal $name is
67           emitted by the remote object, the subroutine $coderef will be
68           invoked, and passed the parameters from the signal.
