Examples of org.apache.lenya.workflow.Transition

org.apache.lenya.workflow.Transition
A transition describes the switching of a workflow instance from one state to another. A transition has
- a source state,
- a destination state,
- an event,
- a set of conditions,
- a set of assignments.
Additionally, a transition can be marked as synchronized.
