NAME

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

SYNOPSIS

         my $service = $bus->get_service("org.freedesktop.DBus");
         my $object = $service->get_object("/org/freedesktop/DBus");

         print "Names on the bus {\n";
         foreach my $name (sort @{$object->ListNames}) {
             print "  ", $name, "\n";
         }
         print "}\n";

DESCRIPTION

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

METHODS

my $object = Net::DBus::RemoteObject->new($service, $object_path[, $interface], \%params);
Creates a new handle to a remote object. The $service parameter is an instance of the
Net::DBus::RemoteService method, and $object_path is the identifier of an object exported by this
service, for example "/org/freedesktop/DBus". For remote objects which implement more than one
interface it is possible to specify an optional name of an interface as the third parameter. This is
only really required, however, if two interfaces in the object provide methods with the same name,
since introspection data can be used to automatically resolve the correct interface to call cases
where method names are unique. Rather than using this constructor directly, it is preferable to use
the "get_object" method on Net::DBus::RemoteService, since this caches handles to remote objects,
eliminating unnecessary introspection data lookups.

The %params parameter contains extra configuration parameters for the object. Currently a single
parameter is supported, "timeout" which takes a value in milliseconds to use as the timeout for
method calls on the object.

my $object = $object->as_interface($interface);
Casts the object to a specific interface, returning a new instance of the Net::DBus::RemoteObject
specialized to the desired interface. It is only necessary to cast objects to a specific interface,
if two interfaces export methods or signals with the same name, or the remote object does not support
introspection.

my $service = $object->get_service
Retrieves a handle for the remote service on which this object is attached. The returned object is an
instance of Net::DBus::RemoteService

my $path = $object->get_object_path
Retrieves the unique path identifier for this object within the service.

my $object = $object->get_child_object($subpath, [$interface])
Retrieves a handle to a child of this object, identified by the relative path $subpath. The returned
object is an instance of "Net::DBus::RemoteObject". The optional $interface parameter can be used to
immediately cast the object to a specific type.

my $sigid = $object->connect_to_signal($name, $coderef);
Connects a callback to a signal emitted by the object. The $name parameter is the name of the signal
within the object, and $coderef is a reference to an anonymous subroutine. When the signal $name is
emitted by the remote object, the subroutine $coderef will be invoked, and passed the parameters from
the signal. A unique $sigid will be returned, which can be later passed to "disconnect_from_signal"
to remove the handler

$object->disconnect_from_signal($name, $sigid);
Disconnects from a signal emitted by the object. The $name parameter is the name of the signal within
the object. The $sigid must be the unique signal handler ID returned by a previous
"connect_to_signal" method call.
