NAME

Net::DBus::ASyncReply - asynchronous method reply handler

SYNOPSIS

   use Net::DBus::Annotation qw(:call);
 
   my $object = $service->get_object("/org/example/systemMonitor");
 
   # List processes & get on with other work until
   # the list is returned.
   my $asyncreply = $object->list_processes(dbus_call_async, "someuser");
 
   while (!$asyncreply->is_ready) {
     ... do some background work..
   }
 
   my $processes = $asyncreply->get_result;
 
 

DESCRIPTION

This object provides a handler for receiving asynchronous method replies. An asynchronous reply object is generated when making remote method call with the "dbus_call_async" annotation set.

METHODS

$asyncreply->discard_result;

Indicates that the caller is no longer interested in recieving the reply & that it should be discarded. After calling this method, this object should not be used again.

$asyncreply->wait_for_result;

Blocks the caller waiting for completion of the of the asynchronous reply. Upon returning from this method, the result can be obtained with the "get_result" method.

my $boolean = $asyncreply->is_ready;

Returns a true value if the asynchronous reply is now complete (or a timeout has occurred). When this method returns true, the result can be obtained with the "get_result" method.

$asyncreply->set_notify($coderef);

Sets a notify function which will be invoked when the asynchronous reply finally completes. The callback will be invoked with a single parameter which is this object.

my @data = $asyncreply->get_result;

Retrieves the data associated with the asynchronous reply. If a timeout occurred, then this method will throw an exception. This method can only be called once the reply is complete, as indicated by the "is_ready" method returning a true value. After calling this method, this object should no longer be used.
