Constructor Summary
protected TransitionableState(Flow flow, String id)
     Create a new transitionable state.

Method Summary
protected void appendToString(ToStringCreator creator)

public void exit(RequestControlContext context)
     Exit this state.
public ActionList getExitActionList()
     Returns the list of actions executed by this state when it is exited.
public Transition getRequiredTransition(RequestContext context)
     Get a transition in this state for given flow execution request context.
public TransitionSet getTransitionSet()
     Returns the set of transitions.
public TransitionDefinition[] getTransitions()

public ViewSelection onEvent(RequestControlContext context)
     Inform this state definition that an event was signaled in it.
public ViewSelection reenter(RequestControlContext context)
     Re-enter this state.

Constructor Detail
TransitionableState
protected TransitionableState(Flow flow, String id) throws IllegalArgumentException(Code)
Create a new transitionable state.
Parameters:
  flow - the owning flow
Parameters:
  id - the state identifier (must be unique to the flow)
throws:
  IllegalArgumentException - when this state cannot be added to givenflow, for instance when the id is not unique
See Also:   State.State(FlowString)
See Also:   TransitionableState.getTransitionSet()

Method Detail
appendToString
protected void appendToString(ToStringCreator creator)(Code)

exit
public void exit(RequestControlContext context)(Code)
Exit this state. This is typically called when a transition takes the flow out of this state into another state. By default just executes any registered exit actions.
Parameters:
  context - the flow control context

getExitActionList
public ActionList getExitActionList()(Code)
Returns the list of actions executed by this state when it is exited. The returned list is mutable. the state exit action list

getRequiredTransition
public Transition getRequiredTransition(RequestContext context) throws NoMatchingTransitionException(Code)
Get a transition in this state for given flow execution request context. Throws and exception when there is no corresponding transition.
throws:
  NoMatchingTransitionException - when a matching transition cannotbe found

getTransitionSet
public TransitionSet getTransitionSet()(Code)
Returns the set of transitions. The returned set is mutable.

getTransitions
public TransitionDefinition[] getTransitions()(Code)

onEvent
public ViewSelection onEvent(RequestControlContext context) throws NoMatchingTransitionException(Code)
Inform this state definition that an event was signaled in it. The signaled event is the last event available in given request context ( RequestContext.getLastEvent ).
Parameters:
  context - the flow execution control context the selected view
throws:
  NoMatchingTransitionException - when a matching transition cannotbe found

reenter
public ViewSelection reenter(RequestControlContext context)(Code)
Re-enter this state. This is typically called when a transition out of this state is selected, but transition execution rolls back and as a result the flow reenters the source state.
By default, this just calls enter().
Parameters:
  context - the flow control context in an executing flow (a clientinstance of a flow) a view selection containing model and view information needed torender the results of the state processing
