Class::Workflow::YAML - Load workflow definitions from YAML files.
This module lets you easily load workflow definitions from YAML files. YAML is nice for this because its much more concise than XML, and allows clean embedding of perl code....

Class::Workflow::State - An instance's position in the workflow.
This is an abstract role for state implementations. In order ot work properly all states...

Class::Workflow::Context - The context in which a transition is being applied (optional).
If you need to pass arbitrary arguments to the workflow, a context object will usually help. This specific context object provides "stash", a writable hash which is essentially free-for-all. Class::Workflow::Context doesn't provide much and should ge...

Class::Workflow::Instance - An instance in a workflow, with state and history.
A workflow instance encapsulates the current state and workflow history on behalf of some parent object that needs state management. In Class::Workflow these instances are functionally pure, that is they don't change but instead derive their parent c...

Class::Workflow::Cookbook - Common recipes with Class::Workflow.
Class::Workflow is a generic, abstract system. This document is supposed to fill the gap between that and the practical, for a few simple examples....

Class::Workflow::Transition - A function over an instance.
This is the base role for transition implementations. every transition object must comply to it's interface, and furthermore must also use the "derive_and_accept_instance" method to return a derived instance at the end of the operation....

Class::Workflow::Util::Delta - calculate deltas between workflow instances
Usually you need to calculate deltas between workflow instances in order to normalize the database of history changes so that there are no duplicate fields. This module lets you create an object that represents the change between any two instances (n...

Class::Workflow::Instance::Simple - A Workflow instance objects to work with the other ::Simple classes.
This method adds an error field to Class::Workflow::Instance. In the event that you want to make errors non-fatal, but instead encapsulate errors in the workflow using their own states, "error" just becomes a regular field. Class::Workflow::Transitio...

Class::Workflow::Transition::Strict - Verify that the transition is in the instance's current state before applying.
This mixin role provides a "before" in Moose wrapper around the "apply" method, that verifies that the transition is present in the current state of the instance. Normally you use the state introspection methods to retrieve transition objects from th...

Class::Workflow::State::AcceptHooks - Add hooks that are fired when the state accepts an instance.
When an instance enters a state it is sometimes convenient to call hooks, for e.g. notification or logging purposes. These hooks should not have any side effect that directly affects the workflow instance in any way - for that functionality you shoul...

Class::Workflow::State::TransitionSet - A state that implements transition meta data using Set::Object.
This is a concrete role that implements "transitions", "has_transition" and "has_transitions" as required by Class::Workflow::State, and adds "add_transitions", "remove_transitions" and "clear_transitions" as well. Transition storage is implemented i...

Class::Workflow::Transition::Validate - Provide a hook for validating a transition (conditionals, input validators, etc).
This role will call the "validate" method at the appropriate time. "validate" receives the same arguments as "apply", and is expected to die if any of the parameters for the transition are invalid. Technically, this role doesn't do much more than add...

Class::Workflow::State::TransitionHash - Implement transition metadata with a hash.
This is a concrete role that implements "transitions", "has_transition" and "has_transitions" as required by Class::Workflow::State, and adds "add_transitions", "remove_transitions", "clear_transitions" , "get_transitions", and "get_transition" as we...

Class::Workflow::Transition::Deterministic - A transition which knows which state it leads to.
This role provides a base role for transitions which know their target state. It overrides "apply" with a default implementation that will derive an instance for you, setting "state" automatically, appending the return value from "apply_body" to that...
