# Package com.opensymphony.xwork2

Main XWork interfaces and classes.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  Action | All actions may implement this interface, which exposes the `execute()` method.
  ActionEventListener | Provides hooks for handling key action events
  ActionInvocation | An `ActionInvocation` represents the execution state of an `Action`.
  ActionProxy | ActionProxy is an extra layer between XWork and the action so that different proxies are possible.
  ActionProxyFactory | The `ActionProxyFactory` is used to create `ActionProxy`s to be executed.
  FileManager | Basic interface to access file on the File System and to monitor changes
  FileManagerFactory | Factory that creates FileManager, default to `DefaultFileManager`
  LocaleProvider | Indicates that the implementing class can provide its own `Locale`.
  LocaleProviderFactory | Allows delegate creation of `LocaleProvider` to another implementation provided by a user.
  LocalizedTextProvider |
  ModelDriven<T> | ModelDriven Actions provide a model object to be pushed onto the ValueStack in addition to the Action itself, allowing a FormBean type approach like Struts.
  Preparable | Preparable Actions will have their `prepare()` method called if the `PrepareInterceptor` is applied to the ActionConfig.
  ResourceBundleTextProvider | Extension Interface for TextProvider to help supporting ResourceBundles.
  Result | All results (except for `Action.NONE`) of an `Action` are mapped to a View implementation.
  TextProvider | Provides access to `ResourceBundle`s and their underlying text messages.
  TextProviderFactory |
  Unchainable | Simple marker interface to indicate an object should not have its properties copied during chaining.
  UnknownHandler | Handles cases when the result or action is unknown.
  UnknownHandlerManager | An unknown handler manager contains a list of UnknownHandler and iterates on them by order
  Validateable | Provides an interface in which a call for a validation check can be done.

- Class Summary
  Class | Description
  --- | ---
  ActionChainResult | This result invokes an entire other action, complete with it's own interceptor stack and result.
  ActionContext | The ActionContext is the context in which an `Action` is executed.
  ActionSupport | Provides a default implementation for the most common actions.
  CompositeTextProvider | This is a composite `TextProvider` that takes in an array or `List` of `TextProvider`s, it will consult each of them in order to get a composite result.
  DefaultActionInvocation | The Default ActionInvocation implementation
  DefaultActionProxy | The Default ActionProxy implementation
  DefaultActionProxyFactory | Default factory for `ActionProxyFactory`.
  DefaultLocaleProvider | Default implementation of `LocaleProvider`
  DefaultLocaleProviderFactory |
  DefaultTextProvider | DefaultTextProvider gets texts from only the default resource bundles associated with the default bundles.
  DefaultUnknownHandlerManager | Default implementation of UnknownHandlerManager
  ObjectFactory | ObjectFactory is responsible for building the core framework objects.
  StrutsTextProviderFactory | This factory enables users to provide and correctly initialize a custom TextProvider.
  TestNGXWorkTestCase | Base test class for TestNG unit tests.
  TextProviderSupport | Default TextProvider implementation.
  ValidationAwareSupport | Provides a default implementation of ValidationAware.
  XWorkConstants | Deprecated
  XWorkJUnit4TestCase |
  XWorkTestCase | Base JUnit TestCase to extend for XWork specific JUnit tests.
