Net::DBus::Callback - a callback for receiving reactor events
SYNOPSIS
use Net::DBus::Callback;
# Assume we have a 'terminal' object and its got a method
# to be invoked everytime there is input on its terminal.
#
# To create a callback to invoke this method one might use
my $cb = Net::DBus::Callback->new(object => $terminal,
method => "handle_stdio");
# Whatever is monitoring the stdio channel, would then
# invoke the callback, perhaps passing in a parameter with
# some 'interesting' data, such as number of bytes available
$cb->invoke($nbytes)
#... which results in a call to
# $terminal->handle_stdio($nbytes)
DESCRIPTION
This module provides a simple container for storing details
about a callback to be invoked at a later date. It is used
when registering to receive events from the Net::DBus::Reactor
class
METHODS
my $cb = Net::DBus::Callback->new(method => $name, [args => \@args])
Creates a new callback object, for invoking a plain old function. The "method"
parameter should be the fully qualified function name to invoke, including the
package name. The optional "args" parameter is an array reference of parameters
to be pass to the callback, in addition to those passed into the "invoke" method.
Creates a new callback object, for invoking a method on an object. The "method"
parameter should be the name of the method to invoke, while the "object" parameter
should be a blessed object on which the method will be invoked. The optional "args"
parameter is an array reference of parameters to be pass to the callback, in addition
to those passed into the "invoke" method.
$cb->invoke(@args)
Invokes the callback. The argument list passed to the callback
is a combination of the arguments supplied in the callback
constructor, followed by the arguments supplied in the "invoke"
method.
