NAME

Workflow::Persister::SPOPS - Persist workflows using SPOPS

VERSION

This documentation describes version 1.07 of this package

SYNOPSIS

<persister name="SPOPSPersister"
           class="Workflow::Persister::SPOPS"
           workflow_class="My::Persist::Workflow"
           history_class="My::Persist::History"/>

DESCRIPTION

Overview

Use a SPOPS classes to persist your workflow and workflow history information. Configuration is simple: just specify the class names and everything else is done.

We do not perform any class initialization, so somewhere in your server/process startup code you should have something like:

my $config = get_workflow_and_history_config();
SPOPS::Initialize->process({ config => $config });

This will generate the classes named in the persister configuration.

SPOPS Configuration

NOTE: The configuration for your workflow history object must use the SPOPS::Tool::DateConvert to translate the 'history_date' field into a DateTime object. We assume when we fetch the history object that this has already been done.

METHODS

init ( \%params)

This method initializes the SPOPS persistance entity.

It requires that a workflow_class and a history_class are specified. If not the case Workflow::Exceptions are thrown.

create_workflow

Serializes a workflow into the persistance entity configured by our workflow.

Takes a single parameter: a workflow object

Returns a single value, a id for unique identification of out serialized workflow for possible deserialization.

fetch_workflow

Deserializes a workflow from the persistance entity configured by our workflow.

Takes a single parameter: the unique id assigned to our workflow upon serialization (see "create_workflow").

Returns a hashref consisting of two keys:

  • state, the workflows current state

  • last_update, date indicating last update

update_workflow

Updates a serialized workflow in the persistance entity configured by our workflow.

Takes a single parameter: a workflow object

Returns: Nothing

create_history

Serializes history records associated with a workflow object

Takes two parameters: a workflow object and an array of workflow history objects

Returns: provided array of workflow history objects upon success

fetch_history

Deserializes history records associated with a workflow object

Takes a single parameter: a workflow object

Returns an array of workflow history objects upon success
