Description

Interface Summary

FlowExecution	Represents a client instance of an executing flow.
FlowExecutionListener	Interface to be implemented by objects that wish to listen and respond to the lifecycle of a FlowExecution.
FlowExecutionListenerCriteria	Strategy interface that determines if a flow execution listener should attach to executions of a specific flow definition.
FlowExecutionListenerLoader	A strategy interface for loading a set of FlowExecutionListener's for a provided flow definition.
FlowExecutionStorage	Storage strategy for flow executions.
TransactionSynchronizer	Interface to demarcate an application transaction for a flow execution.

Class Summary

AbstractTokenTransactionSynchronizer	Abstract base class to ease implementation of synchronizer token based transaction synchronizers.
ClientContinuationFlowExecutionStorage	Flow execution storage implementation that will store a flow execution as a continuation on the client side.
ExternalEvent	Abstract superclass for events encapsulating a request coming into a flow execution from an external source (client).
FlowExecutionContinuation	Helper class that aides in handling a flow execution as if it was a continuation.
FlowExecutionImpl	Default implementation of FlowExecution that uses a stack-based data structure to manage flow sessions.
FlowExecutionListenerAdapter	An abstract adapter class for listeners (observers) of flow execution lifecycle events.
FlowExecutionListenerCriteriaFactory	Static factory for producing common flow execution listener criteria.
FlowExecutionListenerCriteriaFactory.FlowIdFlowExecutionListenerCriteria	A flow execution listener criteria implementation that matches flows with a specified id.
FlowExecutionListenerCriteriaFactory.WildcardFlowExecutionListenerCriteria	A flow execution listener criteria implementation that matches for all flows.
FlowExecutionListenerList	A strongly typed listener list class for FlowExecutionListeners.
FlowExecutionManager	A manager for the executing flows of the application.
FlowScopeTokenTransactionSynchronizer	The default transaction synchronizer implementation.
FlowSessionImpl	Implementation of the FlowSession interfaced used internally by the FlowExecutionImpl.
StateContextImpl	Default state context implementation used internally by the web flow system.
TextToFlowExecutionListenerCriteria	Converter that converts an encoded string representation of a flow execution listener criteria object to an object instance.

Exception Summary

EnterStateVetoException	Exception thrown to veto entering of a state in a web flow.
FlowExecutionStorageException	Exception signaling a fatal, technical problem while accessing a flow execution storage.
NoSuchFlowExecutionException	Thrown when no flow execution exists by the specified flowExecutionId.

Package org.springframework.webflow.execution Description

This package provides classes and interfaces supporting managed flow execution. The central concept defined by this package is the FlowExecution.

The following classes and interfaces are of particular interest to the user of the web flow system:

• FlowExecutionManager - A manager class clients (e.g. controllers) can use to manage flow execution.
• FlowExecutionStorage - A storage strategy interface used by the flow execution manager to store the state of an ongoing flow execution.
• TransactionSynchronizer - A strategy interface used by the flow execution to manage application transactions. The implementation is configurable at the level of the flow execution manager.
• FlowExecutionListener - The listener interface to be implemented by objects that are interested in flow execution lifecycle events. The class FlowExecutionListenerAdapter provides an adapter to ease subclassing.
