Contents

discard_result

Usage:

$asyncreply->discard_result;

This tells the program that the caller is no longer interested in any further responses. Once this is called, the associated object should no longer be used.

wait_for_result

Usage:

$asyncreply->wait_for_result;

This holds or pauses the caller until the remote method has returned results. Once this returns, you can collect the returned data using the 'get_result' method.

is_ready

Usage:

my $boolean = $asyncreply->is_ready;
MADI: Would a good example of this be something like "while (!$asyncreply->is_ready) { &display_progress_bar; } # Where 'display_progress_bar' is some yet-written method..." ?

This returns a boolean value of (TRUE/0??) when the remote method has returned data or timed out. Once true, you can collect the data or error using the 'get_result' method.

set_notify

Usage:

my $coderef=\&some_method();
$asyncreply->set_notify($coderef);

This takes a reference to a method and executes it when the remote method has completed. The referenced method will be called with only a reference to this object.

MADI: Confirm that I understand this right. If I do, ask Daniel if it would be reasonable/safe/possible to take an array of extra variables that could be passed to the referenced method. Ie:

Usage:

sub set_notify {
        my $self = shift;
        my $cb = shift;
        my @vars = @_;
 
        $self->{pending_call}->set_notify(sub
        {
                my $pending_call = shift;
 
                &$cb($self, @vars);
        });
}

Call with:

$asyncreply->set_notify($coderef, $conf, $foo, $bar);

get_result

Usage:

my @data = $asyncreply->get_result;

This returns the data from the remote method call. If the remote method call timed out, this method will throw an exception. This should only be called after the 'is_ready' method returns a true value or the 'wait_for_result' method has returned. Once this method is called, this object should no longer be used.

MADI: In the case of an exception, could/should a program run this in an 'eval'?
