Description

Interface Summary

FormBehavior	Common interface extended by IForm and FormSupport.
IActionListener	Defines a listener to an IDirect component, which is way to get behavior when the component's URL is triggered (or the form containing the component is submitted).
IAsset	Representation of a asset (GIF, JPEG, etc.) that may be owned by a IComponent.
IBeanProvider	An object that provides a component with access to helper beans.
IBinding	A binding is the mechanism used to provide values for parameters of specific IComponent instances.
IComponent	Defines an object which may be used to provide dynamic content on a Tapestry web page.
IDirect	Interface that defines classes that may be messaged by the direct service.
IDirectEvent	Interface that defines classes that may be invoked directly by the event service.
IDynamicInvoker	Represents "something" that can cause dynamic XHR/JSON requests to be executed as a result of whatever actions the thing that it is attached to normally does.
IEngine	Defines the core, session-persistant object used to run a Tapestry application for a single client (each client will have its own instance of the engine).
IExternalPage	Defines a page which may be referenced externally via a URL using the ExternalService.
IForm	A generic way to access a component which defines an HTML form (or, perhaps, other similar constructs, such as a WML Go).
IJSONRender	Defines a component/page/class that is capable of rendering json responses via IJSONWriter writers.
IMarkupWriter	Defines an object that can write markup (XML, HTML, XHTML) style output.
INamespace	Organizes different libraries of Tapestry pages, components and services into "frameworks", used to disambiguate names.
IPage	A root level component responsible for generating an entire a page within the application.
IRender	An element that may be asked to render itself to an IMarkupWriter using a IRequestCycle.
IRequestCycle	Controller object that manages a single request cycle.
IScript	An object that can convert a set of symbols into a collection of JavaScript statements.
IScriptProcessor	Defines methods needed by a IScriptto execute.
ITemplateComponent	Extra interface implemented by BaseComponent and inherited by BasePage, used to allow them to add contents from their templates.
NestedMarkupWriter	A writer that is created by, and nested within, another markup writer.
PageRenderSupport	Extends IScriptProcessor with a handful of additional methods needed when rendering a page response.
SessionStoreOptimized	Optional interface implemented by Application State Objects.

Class Summary

AbstractComponent	Abstract base class implementing the IComponentinterface.
AbstractPage	Abstract base class implementing the IPageinterface.
ApplicationServlet	Links a servlet container with a Tapestry application.
BaseComponent	Base implementation for most components that use an HTML template.
BaseSessionStoreOptimized	Base implementation of SessionStoreOptimized.
Constants	Constant values used inside Tapestry.
RedirectFilter	Filter used to redirect a root context URL (i.e., "/context" or "/context/" to the Tapestry application servlet (typically, "/context/app").
Tapestry	A placeholder for a number of (static) methods that don't belong elsewhere, as well as a global location for static constants.
TapestryConstants
TapestryUtils	Constants and static methods.

Exception Summary

BindingException	A general exception describing an IBinding and an IComponent.
PageNotFoundException	Subclass of ApplicationRuntimeException thrown when a requested page does not exist.
PageRedirectException	Exception thrown by a component or IEngineService that wishes to force the application to a particular page.
RedirectException	Exception thrown to force a redirection to an arbitrary location.
RenderRewoundException	A special subclass of ApplicationRuntimeException that can be thrown when a component has determined that the state of the page has been rewound.
StaleLinkException	Exception thrown by an IEngineService when it discovers that the an action link was for an out-of-date version of the page.
StaleSessionException	Exception thrown by an IEngineService when it discovers that the HttpSession has timed out (and been replaced by a new, empty one).

Package org.apache.tapestry Description

Tapestry is a comprehensive web application framework, written in Java.

Tapestry is not an application server. It is designed to be used inside an application server.

Tapestry is not an application. Tapestry is a framework for creating web applications.

Tapestry is not a way of using JavaServer Pages. Tapestry is an alternative to using JavaServer Pages.

Tapestry is not a scripting environment. Tapestry uses a component object model, not simple scripting, to create highly dynamic, interactive web pages.

Tapestry is based on the Java Servlet API version 2.2.

Tapestry uses a sophisticated component model to divide a web application into a hierarchy of components. Each component has specific responsibilities for rendering web pages (that is, generating a portion of an HTML page) and responding to HTML queries (such as clicking on a link, or submitting a form).

The Tapestry framework takes on virtually all of the responsibilities for managing application flow and server-side client state. This allows developers to concentrate on the business and presentation aspects of the application.
