Description

Interface Summary

Component	A Component is created by a ComponentTag and stored into the users Session.
Form	Sends events to FormListeners, e.g.
FormListener	FormListeners are notified about form changes.
LifeCycle	Lifecycle of WCF Components
NestableComponent	A Component that may be nested inside another component.
Renderable	model of the RenderTag
RenderListener	Part of a component that wants to be informed about the rendering.
RoleExprHolder
Visible	Components that implement this interface will not be rendered if isVisible returns false.

Class Summary

ComponentSupport	default implementation of a component
ComponentTag	initializes the component during doEndTag()
FormSupport	default implementation of Form.
NestableComponentSupport	default implementation of NestableComponent
RendererParameters	keeps track of stylesheet parameters for the RendererTag.
RendererParameterTag	Adds an XSL parameter for the transformation.
RendererTag	renders a Component via xsl stylesheet.
RoleExprTag	A conditional tag that evaluates its body if the roleExpr is successful

Package com.tonbeller.wcf.component Description

WCF Component interfaces.

Renderable

The RendererTag is associated with a Renderable instance (it will lookup the Renderable in the users session). It renders the Document retrieved by getDocument() via an XSLT stylesheet. There may be parameters for the stylesheed provided by the RendererParameterTag, local (valid for a single transformation) or global (valid for all transformations). If the Renderable happens to implement the Visible interface, it will be rendered only if isVisible() returns true.

Component

A Component is created by a ComponentTag and rendered by a RenderTag. A Component produces a DOM that is rendered via XSL stylesheet.

An XmlComponent is a component that holds a DOM, NodeHandlers may be attached to the Elements of the XmlComponents DOM.

Form

A Form instance is where com.tonbeller.wcf.component.FormListeners can be registered -- they receive events

• validate - the data entered by the user are validated and set into the model (OK Button)
• revert - the models current state shall be presented to the user (Cancel Button)

Form implements the FormListener interface, so forms may listen to each other. For example, the selection in a TableComponent is read when the user presses the OK button in a FormComponent To register the table's form is registered with the FormComponent do:

  FormComponent form = ...
  TableComponent table = ...
  form.getForm().addFormListener(table.getForm());
