NAME ^

MooseX::AbstractFactory - AbstractFactory behaviour as a Moose extension

VERSION ^

version 0.004003

SYNOPSIS ^

        package My::Factory;
        use MooseX::AbstractFactory;

        # optional role(s) that define what the implementations should implement

        implementation_does [ qw( My::Factory::Implementation::Requires ) ];
        implementation_class_via sub { 'My::Implementation::' . shift };

        # -------------------------------------------------------------
        package My::Implementation::One;
        use Moose;

        has connection => (is => 'ro', isa => 'Str');

        sub tweak_connection {
                ...
        }


        # -------------------------------------------------------------
        package My::Factory::Implementation::Requires;
        use Moose::Role;
        requires 'tweak_connection';


        # -------------------------------------------------------------
        package main;
        use My::Factory;

        my $imp = My::Factory->create('One',
                { connection => 'Type1' },
        );

DESCRIPTION ^

Implements an AbstractFactory as a Moose extension

METHODS ^

create()

Returns an instance of the requested implementation.

    use MooseX::AbstractFactory;

        my $imp = My::Factory->create(
                'Implementation',
                { connection => 'Type1' },
        );

implementation_does

Syntactic sugar to define a list of roles each implementation must consume.

implementation_class_via

Syntactic sugar to provide a sub to generate the implementation class name: e.g.:

    use MooseX::AbstractFactory;
    implementation_class_via sub { 'My::Implementation::' . shift };

and then

    my $imp = My::Factory->create("ClassA");

    # $imp->isa "My::Implementation::ClassA"

The default behaviour is to prepend the factory class name, so in the above example (without the implementation_class_via) the implementation class would be "My::Factory::ClassA".

init_meta

Overrides Moose's init_meta and applies MooseX::AbstractFactory::Role.

DIAGNOSTICS ^

No implementation provided

If the factory class's new() method doesn't get an implementation passed, then it will die with the above error.

Invalid implementation class %s: %s"

The implementation passed to the factory class mapped to a class that doesn't exist.
