SYNOPSIS

  # in a startup script somewhere ...

  use IOC;
  use IOC::Service::Parameterized;
  use IOC::Registry;
  use MooseX::IOC;

  {
      my $container = IOC::Container->new('MyProject');
      $container->register(IOC::Service::Literal->new('log_file' => "logfile.log"));
      $container->register(IOC::Service->new('FileLogger' => sub {
          my $c = shift;
          return FileLogger->new($c->get('log_file'));
      }));

      my $reg = IOC::Registry->new;
      $reg->registerContainer($container);
  }

  # in a .pm file somewhere ...

  package MyApplication;
  use Moose;

  has 'logger' => (
      metaclass => 'IOC',
      is        => 'ro',
      isa       => 'FileLogger',
      service   => '/MyProject/FileLogger',
  );

  # in a script file somewhere ...

  my $app = MyApplication->new;
  $app->logger; # automatically gotten from IOC

DESCRIPTION

The "service" option can be in one of the following formats:

IOC::Registry path string

This is the simplest version available, it is simply a path string which can be passed to IOC::Registry's "locateService" method.

IOC::Registry path string and parameters

This version is for use with IOC::Service::Parameterized services, and allows you to pass additional parameters to the "locateService" method. It looks like this:

  has 'logger' => (
      metaclass => 'IOC',
      is        => 'ro',
      isa       => 'FileLogger',
      service   => [ '/MyProject/FileLogger' => (log_file => 'foo.log') ],
  );
    

CODE reference

The last version is the most flexible, it is CODE reference which is expected to return an ARRAY ref similar to the above version.

  has 'logger' => (
      metaclass => 'IOC',
      is        => 'ro',
      isa       => 'FileLogger',
      lazy      => 1,
      service   => sub {
          my $self = shift;
          [ '/MyProject/FileLogger' => (
                log_file => $self->log_file
            ) ]
      },
  );
    

If the "service" is not found and a "default" option has been set, then it will return the value in "default". This can be useful for writing code which can potentially be run both under IOC and not under IOC.
