Astrolabe.Workflow 1.1.0

Astrolabe.Workflow

This library provides abstractions for implementing various tasks which fall under the umbrella of "workflow":

• Declarative rule based triggering of actions - e.g. automated sending emails
• Declarative security for user triggered actions - e.g. provide lists of allowed user triggerable actions and secure them if triggered by the user.
• Encourages efficient bulk operations

The workflow executor

A workflow executor instance is responsible for:

• Loading data (possibly in bulk)
• Check rule based triggers and queue up actions
• Apply the actions which have been user triggered or automatically queued.

The class AbstractWorkflowExecutor<TContext, TLoadContext, TAction> provides a good base for implementing a workflow executor given the 3 type parameters with the following meanings.

TContext

This type needs to carry all the data required for editing a single entity along with any associated entities, e.g. Audit Logs.

TAction

A class which describes all the actions which can be performed, including their parameters if required.

TLoadContext

This class should contain the data required to do a bulk load of data into TContext instances. Usually this is at least a list of id's for the entities to load.
