NAME ^

MooseX::Event::Role::ClassMethods - Make MooseX::Event methods available as class methods on a singleton

VERSION ^

version v0.2.0

SYNOPSIS ^

  package Example {
      use MooseX::Singleton;
      use MooseX::Event;
      
      with 'MooseX::Event::Role::ClassMethods';
      
      has_event 'pinged';
      
      sub ping {
          my $self = shift;
          $self->emit('pinged');
      }
  }
  
  Example->on( pinged => sub { say "Got a ping!" } );
  Example->on( pinged => sub { say "Got another ping!" } );
  Example->ping; # prints "Got a ping!" and "Got another ping!"
  Example->remove_all_listeners( "pinged" ); # Remove all of the pinged listeners
  Example->once( pinged => sub { say "First ping." } );
  Example->ping; Example->ping; # Only prints "First ping." once
  my $listener = Example->on( pinged => sub { say "Ping" } );
  Example->remove_listener( pinged => $listener );
  Example->ping(); # Does nothing

DESCRIPTION ^

Sometimes it's handy to be able to call object methods directly on a singleton class, without having to call instance yourself. This wraps up the MooseX::Event Role to allow this. Your class must provide an instance method that returns the singleton object. One way to do this is with the MooseX::Singleton class, as in the example, but you can easily role your own if you prefer.
