Net::DBus::Annotation − annotations for changing behaviour of APIs
use Net::DBus::Annotation qw(:call);
my $object = $service−>get_object("/org/example/systemMonitor");
# Block until processes are listed
my $processes = $object−>list_processes("someuser");
# Just throw away list of processes, pretty pointless
# in this example, but useful if the method doesn't have
# a return value
$object−>list_processes(dbus_call_noreply, "someuser");
# List processes & get on with other work until
# the list is returned.
my $asyncreply = $object−>list_processes(dbus_call_async, "someuser");
... some time later...
my $processes = $asyncreply−>get_data;
This module provides a number of annotations which will be useful when dealing with the DBus APIs. There are annotations for switching remote calls between sync, async and no-reply mode. More annotations may be added over time.
dbus_call_sync
Requests that a method call be performed synchronously, waiting for the reply or error return to be received before continuing.
dbus_call_async
Requests that a method call be performed a−synchronously, returning a pending call object, which will collect the reply when it eventually arrives.
dbus_call_noreply
Requests that a method call be performed a−synchronously, discarding any possible reply or error message.
