The overall system for executing flow definitions.

The central concept defined by this package is the FlowExecution , representing a single instance of an executing flow (also known as a "dialog" or "web conversation").

The following classes and interfaces are of particular interest to the user of the web flow system:

• FlowExecutionRepository - A repository interface used by a flow execution manager to store the state of an ongoing flow execution.
• FlowExecutionListener - The listener interface to be implemented by objects that are interested in flow execution lifecycle events. The class FlowExecutionListenerAdapter provides an adapter to ease subclassing.

This package depends on the webflow root package.
