NAME

Aion::Pleroma - container of aeons

SYNOPSIS

use Aion::Pleroma;

my $pleroma = Aion::Pleroma->new;

$pleroma->get('user') # -> undef
$pleroma->resolve('user') # @-> user is'nt eon!

DESCRIPTION

Implements the dependency container pattern.

An eon is created when requesting from a container via the get or resolve method, or via the eon aspect as a lazy default. Laziness can be canceled via the lazy aspect.

The container is in the $Aion::pleroma variable and can be replaced with local.

The configuration for creating eons is obtained from the PLEROMA config and the annotation file (created by the Aion::Annotation package). The annotation file can be replaced via the INI config.
