NAME
Net::DBus::Annotation - annotations for changing behaviour of APIs
SYNOPSIS
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;
# List processes, with a shorter 10 second timeout, instead of
# the default 60 seconds
my $object->list_processes(dbus_call_timeout, 10 * 1000, "someuser");
DESCRIPTION
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.
METHODS
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.
dbus_call_timeout
Indicates that the next parameter for the method call will specify
the time to wait for a reply in milliseconds. If omitted, then the
default timeout for the object will be used
