java.lang.Object
   org.springframework.webflow.action.AbstractAction
      org.springframework.webflow.action.AbstractBeanInvokingAction

All known Subclasses:   org.springframework.webflow.action.LocalBeanInvokingAction,
AbstractBeanInvokingAction
abstract public class AbstractBeanInvokingAction extends AbstractAction (Code)
Base class for actions that delegate to methods on beans (POJOs - Plain Old Java Objects). Acts as an adapter that adapts an Object method to the Spring Web Flow Action contract.

Subclasses are required to implement the AbstractBeanInvokingAction.getBean(RequestContext) method, returning the bean on which a method should be invoked.
See Also:   BeanInvokingActionFactory
author:
   Keith Donald




Constructor Summary
protected  AbstractBeanInvokingAction(MethodSignature methodSignature)
     Creates a new bean invoking action.

Method Summary
protected  EventdoExecute(RequestContext context)
    
abstract protected  ObjectgetBean(RequestContext context)
     Retrieves the bean to invoke a method on.
protected  MethodInvokergetMethodInvoker()
     Returns the bean method invoker helper.
public  ActionResultExposergetMethodResultExposer()
     Returns the configuration for how bean method return values should be exposed to an executing flow that invokes this action.
public  MethodSignaturegetMethodSignature()
     Returns the signature of the method to invoke on the target bean.
protected  ResultEventFactorygetResultEventFactory()
     Returns the event adaption strategy used by this action.
public  voidsetConversionService(ConversionService conversionService)
     Set the conversion service to perform type conversion of event parameters to method arguments as neccessary.
public  voidsetMethodResultExposer(ActionResultExposer methodResultExposer)
     Configures how bean method return values should be exposed to an executing flow that invokes this action.
public  voidsetResultEventFactory(ResultEventFactory resultEventFactory)
     Set the bean return value->event adaption strategy.


Constructor Detail
AbstractBeanInvokingAction
protected AbstractBeanInvokingAction(MethodSignature methodSignature)(Code)
Creates a new bean invoking action.
Parameters:
  methodSignature - the signature of the method to invoke




Method Detail
doExecute
protected Event doExecute(RequestContext context) throws Exception(Code)



getBean
abstract protected Object getBean(RequestContext context) throws Exception(Code)
Retrieves the bean to invoke a method on. Subclasses need to implement this method.
Parameters:
  context - the flow execution request context the bean on which to invoke methods
throws:
  Exception - when the bean cannot be retreived



getMethodInvoker
protected MethodInvoker getMethodInvoker()(Code)
Returns the bean method invoker helper.



getMethodResultExposer
public ActionResultExposer getMethodResultExposer()(Code)
Returns the configuration for how bean method return values should be exposed to an executing flow that invokes this action.



getMethodSignature
public MethodSignature getMethodSignature()(Code)
Returns the signature of the method to invoke on the target bean.



getResultEventFactory
protected ResultEventFactory getResultEventFactory()(Code)
Returns the event adaption strategy used by this action.



setConversionService
public void setConversionService(ConversionService conversionService)(Code)
Set the conversion service to perform type conversion of event parameters to method arguments as neccessary. Defaults to DefaultConversionService .



setMethodResultExposer
public void setMethodResultExposer(ActionResultExposer methodResultExposer)(Code)
Configures how bean method return values should be exposed to an executing flow that invokes this action. This is optional. By default the bean method return values do not get exposed to the executing flow.



setResultEventFactory
public void setResultEventFactory(ResultEventFactory resultEventFactory)(Code)
Set the bean return value->event adaption strategy. Defaults to SuccessEventFactory , so all bean method return values will be interpreted as "success".
