SYNOPSIS
package Cat;
use Mojo::Base 'Mojo::EventEmitter';
# Emit events
sub poke {
my $self = shift;
$self->emit(roar => 3);
}
package main;
# Subscribe to events
my $tiger = Cat->new;

say 'RAWR!' for 1 .. $times;
});

DESCRIPTION
Mojo::EventEmitter is a simple base class for event emitting objects.
METHODS
Mojo::EventEmitter inherits all methods from Mojo::Base and implements the following new ones.
"emit"
$e = $e->emit('foo');
$e = $e->emit('foo', 123);
Emit event.
"emit_safe"
$e = $e->emit_safe('foo');
$e = $e->emit_safe('foo', 123);
Emit event safely and emit "error" event on failure.
"has_subscribers"
my $success = $e->has_subscribers('foo');
Check if event has subscribers.
"on"
my $cb = $e->on(foo => sub {...});
Subscribe to event.
$e->on(foo => sub {
my ($e, @args) = @_;
...
});
"once"
my $cb = $e->once(foo => sub {...});
Subscribe to event and unsubscribe again after it has been emitted once.
$e->once(foo => sub {
my ($e, @args) = @_;
...
});
"subscribers"
my $subscribers = $e->subscribers('foo');
All subscribers for event.
# Unsubscribe last subscriber
$e->unsubscribe(foo => $e->subscribers('foo')->[-1]);
