When executed, a transition takes a flow execution from its current state, called the source state, to another state, called the target state. A transition may become eligible for execution on the occurence of Event from within a transitionable source state.

When an event occurs within this transition's source TransitionableState, the determination of the eligibility of this transition is made by a TransitionCriteria object called the matching criteria. If the matching criteria returns true, this transition is marked eligible for execution for that event.

Determination as to whether an eligible transition should be allowed to execute is made by a TransitionCriteria object called the execution criteria. If the execution criteria test fails, this transition will roll back and reenter its source state. If the execution criteria test succeeds, this transition will execute and take the flow to the transition's target state.

The target state of this transition is typically specified at configuration time using the target state id. If the target state of this transition needs to be calculated in a dynamic fashion at runtime, set a custom TargetStateResolver
