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;

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.
