=head1 NAME
Daemon::Generic::AnyEvent - Generic daemon framework with AnyEvent.pm
=head1 SYNOPSIS
use Daemon::Generic::AnyEvent;
use Some::Event::Loop::Supported::By::AnyEvent;
@ISA = qw(Daemon::Generic::AnyEvent);
sub gd_preconfig {
# stuff
}
=head1 DESCRIPTION
Daemon::Generic::AnyEvent is a subclass of L<Daemon::Generic> that
predefines some methods:
=over 15
=item gd_run()
Setup a periodic callback to C<gd_run_body()> if there is a C<gd_run_body()>.
Call C<Event::loop()>.
=item gd_setup_signals()
Bind SIGHUP to call C<gd_reconfig_event()>.
Bind SIGINT to call C<gd_quit_event()>.
=back
To use Daemon::Generic::Event, you have to provide a C<gd_preconfig()>
method. It can be empty if you have a C<gd_run_body()>.
Set up your own events in C<gd_preconfig()> and C<gd_postconfig()>.
If you have a C<gd_run_body()> method, it will be called once per
second or every C<gd_interval()> seconds if you have a C<gd_interval()>
method. Unlike in L<Daemon::Generic::While1>, C<gd_run_body()> should
not include a call to C<sleep()>.
