Package org.apache.tapestry5

Root package for Tapestry, containing common interfaces and data types used throughout the framework.

Interface Summary

Interface	Description
Asset	An Asset is any kind of resource that can be exposed to the client web browser.
Binding	A binding is a connection between a component and its container (another component), that allows the embedded component to gain access to resources defined by the container.
Binding2	Extension to Binding that adds a method to access the generic property type.
Block	A block is a collection of static text and elements, and components, derived from a component template.
BooleanHook	Encapsulates a bit of information that can be represented as a boolean.
ClientBodyElement	Extends ClientElement with the concept of a body, a Block that can be rendered to provide the content within.
ClientElement	Interface for any kind of object (typically, a component) that can provide a client-side id, typically used in the generation of client-side (JavaScript) logic.
ComponentAction<T>	An action that is associated with a component.
ComponentEventCallback<T>	Callback interface for a render phase event or ComponentEvent, notified when a non-null value is returned from some event handler method.
ComponentResources	Provides a component instance with the resources provided by the framework.
ComponentResourcesCommon	Operations shared by the public ComponentResources interface and ComponentPageElement interface (on the internal side).
ContextAwareException	An interface implemented by exceptions that get special handling in the default RequestExceptionHandler service.
EventContext	A collection of parameters that may eventually be passed to an event handler method.
ExceptionHandlerAssistant	A contribution to the default RequestExceptionHandler service, this is mapped to an exception class, allowing class specific (based on an inheritance search) handling of an exception.
Field	Defines a field within a form.
FieldTranslator<T>	A wrapper around Translator that combines the translator for a specific Field and (sometimes) an override of the default validation message (used when an input value can't be parsed).
FieldValidationSupport	Services to help with field validation and translation.
FieldValidator<T>	Responsible for validation of a single field.
FormValidationControl	Allows control over the validation concerns of a Form component.
MarkupWriter	An interface used by objects, such as Tapestry components, that need to render themselves as some form of XML markup.
MarkupWriterListener	An interface that allows objects to be alerted after an element is started, and after an element is ended.
NullFieldStrategy	Defines a strategy, used by Field components such as TextField, to handle the case where either the server-side value to be sent (as a string) to the client, or the client-side string passed back up to the server, is null or blank.
OptionGroupModel	Defines a group of related options.
OptionModel	A single option within a OptionGroupModel.
PropertyOverrides	Provides access to blocks and messages used when overriding property labels, and property display or edit blocks.
RadioContainer	A container of Radio components, used to identify the element name used when rendering the individual radio buttons.
Renderable	Base interface for objects that can render markup output using a MarkupWriter.
SelectModel	Defines the possible options and option groups for a <select> [X]HTML element.
SelectModelVisitor	Callback interface that allows for visiting the option groups and option models of a select model in correct order order.
StreamResponse	An alternate response from a component event handler method used to directly provide a stream of data to be sent to the client, rather than indicating what page to send a render redirect request to.
TrackableComponentEventCallback<T>	Extends ComponentEventCallback with a way to determine if the underlying event has been aborted due to a some event returning an acceptable, non-null value.
Translator<T>	Translates between client-side and server-side values.
ValidationDecorator	Deprecated. Deprecated in 5.4 with no replacement.
ValidationTracker	Tracks information related to user input validations.
Validator<C,T>	Used by a Field to enforce a constraint related to a form submission.
ValueEncoder<V>	A ValueEncoder is used to convert server side objects to unique client-side strings (typically IDs) and back.

Class Summary

Class	Description
AbstractOptionModel	Base class for implementing OptionModel.
BaseOptimizedSessionPersistedObject	Base implementation of OptimizedSessionPersistedObject.
BaseValidationDecorator	Base implementation of ValidationDecorator that does nothing.
BindingConstants	Constants for the built-in binding prefixes.
ComponentParameterConstants	Constants for core component parameters defined by Symbol
CookieBuilder	A fluent API to create and write cookies.
CSSClassConstants	Deprecated. Deprecated in 5.4 with no replacement.
EventConstants	Constant values for common event names fired by Tapestry components.
MarkupConstants	Constants used when rendering page markup.
MarkupUtils	Utility methods related to generating markup.
MarkupWriterAdapter	Default, empty implementation of MarkupWriterListener.
MetaDataConstants	Meta-data keys that are applied to components and pages.
PageCallback	A way of capturing the name of a page and the page activation context so that, at a future date, the page can be invoked with that data.
PersistenceConstants	Constants for persistent field strategies.
QueryParameterConstants	Defines constants for common query parameters passed in requests from the client.
SymbolConstants	Defines the names of symbols used to configure Tapestry.
TapestryConstants	Constants needed by end-user classes.

TapestryMarkers	A set of markers used internally by Tapestry when logging in code related to paqes and components.
ValidationTrackerImpl	Standard implementation of ValidationTracker.
ValidationTrackerWrapper	Wrapper around a ValidationTracker that delegates all methods to the wrapped instance.

Enum Summary
