| org.springframework.webflow.engine |
|
The implementation of the core flow definition artifacts that serve the basis of the flow execution engine.
The engine implementation itself is located within the {@link org.springframework.webflow.engine.impl impl} package.
Builders for assembling flow definitions executable by this engine are located within the
{@link org.springframework.webflow.engine.builder builder} package.

| Java Source File Name | Type | Comment |
| ActionExecutionException.java | Class | Thrown if an unhandled exception occurs when an action is executed. |
| ActionExecutor.java | Class | A simple static helper that performs action execution that encapsulates
common logging and exception handling logic. |
| ActionList.java | Class | An ordered, typed list of actions, mainly for use internally by flow artifacts
that can execute groups of actions. |
| ActionState.java | Class | A transitionable state that executes one or more actions when entered. |
| AnnotatedAction.java | Class | An action proxy/decorator that stores arbitrary properties about a target
Action implementation for use within a specific Action
execution context, for example an ActionState definition, a
TransitionCriteria definition, or in a test environment. |
| AnnotatedObject.java | Class | A base class for all objects in the web flow system that support annotation
using arbitrary properties. |
| DecisionState.java | Class | A simple transitionable state that when entered will execute the first
transition whose matching criteria evaluates to true in the
RequestContext context of the current request. |
| EndState.java | Class | A state that ends a flow when entered. |
| Flow.java | Class | A single flow definition. |
| FlowAttributeMapper.java | Interface | A service interface that maps attributes between two flows. |
| FlowExecutionExceptionHandler.java | Interface | A strategy for handling an exception that occurs at runtime during the
execution of a flow definition. |
| FlowExecutionExceptionHandlerSet.java | Class | A typed set of state exception handlers, mainly for use internally by
artifacts that can apply state exception handling logic. |
| FlowVariable.java | Class | A value object that defines a specification for a flow variable. |
| NoMatchingTransitionException.java | Class | Thrown when no transition can be matched given the occurence of an event in
the context of a flow execution request. |
| NullViewSelector.java | Class | Makes a null view selection, indicating no response should be issued. |
| RequestControlContext.java | Interface | Mutable control interface used to manipulate an ongoing flow execution in the
context of one client request. |
| State.java | Class | A point in a flow where something happens. |
| SubflowState.java | Class | A transitionable state that spawns a subflow when executed. |
| TargetStateResolver.java | Interface | A strategy for calculating the target state of a transition. |
| Transition.java | Class | A path from one
TransitionableState state to another
State state .
When executed a transition takes a flow execution from its current state,
called the source state, to another state, called the target
state. |
| TransitionableState.java | Class | Abstract superclass for states that can execute a transition in response to
an event. |
| TransitionCriteria.java | Interface | Strategy interface encapsulating criteria that determine whether
or not a transition should execute given a flow execution request context. |
| TransitionSet.java | Class | A typed set of transitions for use internally by artifacts that can
apply transition execution logic. |
| ViewSelector.java | Interface | Factory that produces a new, configured
ViewSelection object on each
invocation, taking into account the information in the provided flow
execution request context.
Note: this class is a runtime factory. |
| ViewState.java | Class | A view state is a state that issues a response to the user, for
example, for soliciting form input. |
| WildcardTransitionCriteria.java | Class | Transition criteria that always returns true. |
