NAME
AnyEvent::Delay::Simple - Manage callbacks and control the flow of events by AnyEvent
SYNOPSIS
use AnyEvent::Delay::Simple;
my $cv = AE::cv;
delay([
sub { say('1st step'); },
sub { say('2nd step'); die(); },
# never calls because 2nd step failed
sub { say('3rd step'); }],
# calls on error
sub { say('Fail: ' . $@); $cv->send(); },
# calls on success
sub { say('Ok'); $cv->send(); }
);
$cv->recv();
DESCRIPTION
AnyEvent::Delay::Simple manages callbacks and controls the flow of events for AnyEvent. This module inspired by Mojo::IOLoop::Delay.
FUNCTIONS
delay
delay(\@steps, $finish);
delay(\@steps, $error, $finish);
Runs the chain of callbacks, the first callback will run right away, and the next one once the previous callback finishes. This chain will continue until there are no more callbacks, or an error occurs in a callback. If an error occurs in one of the steps, the chain will be break, and error handler will call, if it's defined. Unless error handler defined, error is fatal. If last callback finishes and no error occurs, finish handler will call.
