Interface Summary

Interface	Description
Interceptor	An interceptor is a stateless class that follows the interceptor pattern, as found in javax.servlet.Filter and in AOP languages.
NoParameters	Marker interface to incidate no auto setting of parameters.
ParameterNameAware	This interface is implemented by actions that want to declare acceptable parameters.
PreResultListener	PreResultListeners may be registered with an ActionInvocation to get a callback after the Action has been executed but before the Result is executed.
ScopedModelDriven<T>	Adds the ability to set a model, probably retrieved from a given state.
ValidationErrorAware	ValidationErrorAware classes can be notified about validation errors before DefaultWorkflowInterceptor will return 'inputResultName' result to allow change or not the result name This interface can be only applied to action which already implements ValidationAware interface!
ValidationWorkflowAware	ValidationWorkflowAware classes can programmatically change result name when errors occurred This interface can be only applied to action which already implements ValidationAware interface!

Class Summary

Class	Description
AbstractInterceptor	Provides default implementations of optional lifecycle methods
AliasInterceptor	The aim of this Interceptor is to alias a named parameter to a different named parameter.
ChainingInterceptor	An interceptor that copies all the properties of every object in the value stack to the currently executing object, except for any object that implements Unchainable.
ConversionErrorInterceptor	ConversionErrorInterceptor adds conversion errors from the ActionContext to the Action's field errors.
DefaultWorkflowInterceptor	An interceptor that makes sure there are not validation errors before allowing the interceptor chain to continue.
ExceptionHolder	A simple wrapper around an exception, providing an easy way to print out the stack trace of the exception as well as a way to get a handle on the exception itself.
ExceptionMappingInterceptor	This interceptor forms the core functionality of the exception handling feature.
I18nInterceptor	An interceptor that handles setting the locale specified in a session as the locale for the current action request.
LoggingInterceptor	This interceptor logs the start and end of the execution an action (in English-only, not internationalized).
MethodFilterInterceptor	MethodFilterInterceptor is an abstract Interceptor used as a base class for interceptors that will filter execution based on method names according to specified included/excluded method lists.
MethodFilterInterceptorUtil	Utility class contains common methods used by MethodFilterInterceptor.
ModelDrivenInterceptor	Watches for ModelDriven actions and adds the action's model on to the value stack.
ModelDrivenInterceptor.RefreshModelBeforeResult	Refreshes the model instance on the value stack, if it has changed
ParameterFilterInterceptor	The Parameter Filter Interceptor blocks parameters from getting to the rest of the stack or your action.
ParameterRemoverInterceptor	This is a simple XWork interceptor that allows parameters (matching one of the paramNames attribute csv value) to be removed from the parameter map if they match a certain value (matching one of the paramValues attribute csv value), before they are set on the action.
ParametersInterceptor	This interceptor sets all parameters on the value stack.
PrefixMethodInvocationUtil	A utility class for invoking prefixed methods in action class.
PrepareInterceptor	This interceptor calls prepare() on actions which implement Preparable.
ScopedModelDrivenInterceptor	An interceptor that enables scoped model-driven actions.
StaticParametersInterceptor	This interceptor populates the action with the static parameters defined in the action configuration.
TimerInterceptor	This interceptor logs the amount of time in milliseconds.
