NAME

EV::Bind - Easier Interface To EV's Callbacks

SYNOPSIS

  use EV;
  use EV::Watcher::Bind;

  EV::io_bind($fh, $mask, $callback, @args);

DESCRIPTION

Highly experimental. You've been warned.

EV::Watcher::Bind provides a simple interface to EV.pm's watcher methods that allows you to bind arguments as well as the watcher being created to the callback being registerd.

If you have, for example, an object that you want to use as your callback, you always need to do

  my $obj = ...;
  my @args = (1, 2, 3);
  my $io = EV::io($fh, $mask, sub { $obj->foo(@args) });

With EV::Watcher::Bind, you can do

  my $io = EV::io_bind($fh, $mask, \&foo, $obj, @args);

The functions provided by EV::Watcher::Bind also has the advantage of passing you the EV::Watcher object that caused your callback to execute as the last argument in your callback. In the above example, foo() could have be implemented like so:

  sub foo {
    my ($self, $arg1, $arg2, $arg3, $w) = @_;
    $w->stop;
  }
