NAME
Net::DBus::RemoteService - Access services provided on the bus
SYNOPSIS
my $bus = Net::DBus->find;
my $service = $bus->get_service("org.freedesktop.DBus");
my $object = $service->get_object("/org/freedesktop/DBus");
foreach (@{$object->ListNames}) {
print "$_\n";
}
DESCRIPTION
This object provides a handle to a remote service on the
bus. From this handle it is possible to access objects
associated with the service. If a service is not running,
an attempt will be made to activate it the first time a
method is called against one of its objects.
METHODS
- my $service = Net::DBus::RemoteService->new($bus, $owner, $service_name);
-
Creates a new handle for a remote service. The $bus parameter is an
instance of Net::DBus, $owner is the name of the client providing the
service, while $service_name is the well known name of the service on
the bus. Service names consist of two or more tokens, separated
by periods, while the tokens comprise the letters a-z, A-Z, 0-9 and _,
for example "org.freedesktop.DBus". There is generally no need to call
this constructor, instead the "get_service" method on Net::DBus should
be used. This caches handles to remote services, eliminating repeated
retrieval of introspection data.
- my $bus = $service->get_bus;
-
Retrieves a handle for the bus to which this service is attached.
The returned object will be an instance of Net::DBus.
- my $service_name = $service->get_service_name
-
Retrieves the name of the remote service as known to the bus.
- my $owner_name = $service->get_owner_name;
-
Retrieves the name of the client owning the service at the
time it was connected to.
- my $object = $service->get_object($object_path[, $interface]); =item my $object = $service->get_object($object_path, \%params);
-
Retrieves a handle to the remote object provided by the service with
the name of $object_path. If the optional $interface parameter is
provided, the object will immediately be cast to the designated
interface. NB, it is only necessary to cast an object to a specific
interface if there are multiple interfaces on the object providing
methods with the same name, or the remote object does support
introspection. The returned object will be an instance of Net::DBus::RemoteObject.
An alternate form of the method is available, passing a hash reference
of extra parameters. Valid keys in the hash are "interface" specifying
the interface name to cast to, and "timeout" specifying a timeout in
milliseconds
- my $timeout = $service->timeout(60 * 1000);
-
Sets or retrieves the timeout value which will be used for DBus
requests belongs to this service. The value is in milliseconds.
If the timeout for a service is undefined, then the default
timeout from the bus will apply.
