NAME ^

Workflow::Lite::Registry - A workflow registry

SYNOPSIS ^

  package MyRegistry;

  use namespace::autoclean;
  use Moose;

  extends qw( Workflow::Lite::Registry );

  __PACKAGE__->register(
    Even => 'MyApp::Workflow::Even',
    Odd  => 'MyApp::Workflow::Odd',
  );

  1

  ...

  use MyRegistry;

  my $wf_name = time % 2 == 0 ? 'Even' : 'Odd';
  my @args    = ( foo => 'Foo', bar => 'Bar' );
  my $wf      = MyRegistry->new_workflow( $wf_name => @args );

DESCRIPTION ^

Workflow::Lite::Registry is meant to be used as a base class to application-specific workflow registries that can be used to shorten class names. Workflow::Lite classes are registered and given a short, unique name that can be referenced at a later time. This is probably most advantageous when there are many different workflow classes being used or if workflows need to be used based on configuration or user input.

CLASS ATTRIBUTES ^

_registry

A HashRef that contains the workflow registry.

CLASS METHODS ^

register( $id, $workflow_class )

Registers a new workflow class into the registry under the given id. The workflow class is also loaded for convenience.

workflow_class( $id )

Returns the workflow class that is associated with the given id in the registry.

new_workflow( $id, @args )

Instantiates a new workflow object by looking up the workflow class associated with the given id and then calling new() with the given arguments.

BUGS ^

None are known at this time, but if you find one, please feel free to submit a report to the author.
