NAME
IO::Event::Callback - A closure based API
for
IO::Event
SYNOPSIS
use
IO::Event::Callback;
IO::Event::Callback->new(
$filehanle
,
%callbacks
);
IO::Event::INET::Callback->new(
%socket_info
,
%callbacks
);
IO::Event::UNIX::Callback->new(
%socket_info
,
%callbacks
);
DESCRIPTION
IO::Event::Callback is a wrapper around IO::Event. It provides an alternative interface to using IO::Event.
Instead of defining a class with methods like "ie_input", you provide the callbacks as code references when you create the object.
The keys for the callbacks are the same as the callbacks for IO::Event with the ie_
prefix removed.
EXAMPLE
use
IO::Event::Callback;
my
$remote
= IO::Event::Callback::INET->new(
peeraddr
=>
'10.20.10.3'
,
peerport
=>
'23'
,
input
=>
sub
{
# handle input
},
werror
=>
sub
{
# handdle error
},
eof
=>
sub
{
# handle end-of-file
},
);
