NAME

MooseX::Role::Registry

SYNOPSYS

    package Foo::Registry;
    use Moose;
    with 'MooseX::Role::Registry';

    sub config_file {
        return '/foo_objects.yml';
    }

    sub build_registry_object {
        my $self   = shift;
        my $name   = shift;
        my $values = shift || {};

        return Foo->new({
            name                   => $name,
            %$values
        });
    }

    package main;
    my $registry = Foo::Registry->instance;
    my $foo = $registry->get('bar');

DESCRIPTION

This role watches a file which describes a hashref of objects in yml format. This hashref is called a "registry" because the objects in the hashref can be requested by name using get.

Implementations should be singletons! In other words, when using a class that is derived from MooseX::Role::Registry, you shouldn't call new. Instead, just get the singelton object using the instance method and call get on the result.

REQUIRED SUBCLASS METHODS

config_filename

Returns the filesystem path of the default location of the configuration file that is watched by a given consumer of MooseX::Role::Registry

build_registry_object

A function to create an object of the registy entry

METHODS

get($name)

Returns the registered entity called $name, or undef if none exists.

all

Returns all of the objects stored in the registry. Useful for generic grep() calls.

keys

Returns a list of all of the (lookup) keys of objects currently registered in $self.

registry_fixup

A callback which allows subclasses to modify the hashref of loaded objects before they are stored in memory as part of $self.

DEPENDENCIES

Moose::Role
namespace::autoclean
