Description
Interface Summary | |
---|---|
Action | A command that executes a behavior and returns a logical execution result a calling flow execution can respond to. |
FlowExecution | An execution of a flow definition. |
FlowExecutionContext | Provides contextual information about a flow execution. |
FlowExecutionFactory | An abstract factory for creating flow executions. |
FlowExecutionKeyFactory | A factory for creating flow execution keys. |
FlowExecutionListener | Interface to be implemented by objects that wish to listen and respond to the lifecycle of
flow executions . |
FlowSession | A single, local instantiation of a flow definition launched within an overall flow execution. |
RequestContext | A context for a single request to manipulate a flow execution. |
View | Allows a client to participate in flow execution. |
ViewFactory | A factory for a view that allows the client to participate in flow execution. |
Class Summary | |
---|---|
ActionExecutor | A simple static helper that performs action execution that encapsulates common logging and exception handling logic. |
AnnotatedAction | 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. |
Event | Signals the occurrence of something an active flow execution should respond to. |
FlowExecutionKey | A key that uniquely identifies a flow execution in a managed FlowExecutionRepository . |
FlowExecutionListenerAdapter | An abstract adapter class for listeners (observers) of flow execution lifecycle events. |
FlowExecutionOutcome | An outcome returned by a flow execution when it ends. |
RequestContextHolder | Simple holder class that associates a RequestContext instance with the current thread. |
ScopeType | An enumeration of the core scope types of Spring Web Flow. |
Exception Summary | |
---|---|
ActionExecutionException | Thrown if an unhandled exception occurs when an action is executed. |
EnterStateVetoException | Exception thrown to veto the entering of a state of a flow. |
FlowExecutionException | Base class for exceptions that occur within a flow while it is executing. |
Core, stable abstractions for representing runtime executions of flow definitions.
The central concept defined by this package is the
FlowExecution
interface, which represents
a single instance of a top-level flow definition.
The following classes and interfaces are of particular interest:
FlowExecutionFactory
- An abstract
factory for creating new flow executions.
FlowExecutionRepository
- A DAO
for persisting and restoring existing flow executions.
FlowExecutionListener
- An observer
interface to be implemented by objects that are interested in flow execution
lifecycle events.
This package depends on the definition package.
