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.
