Interface Summary

Interface	Description
AbortingReason	The aborting reason used to abort the current execution.
ComponentCtrl	An addition interface to Component that is used for implementation or tools.
ContentRenderer	Used with AbstractComponent.renderProperties(org.zkoss.zk.ui.sys.ContentRenderer) to generate the component content that will be sent to the client.
DesktopCache	The cache used to store desktops.
DesktopCacheProvider	Used to retrieve a desktop cache (DesktopCache).
DesktopCtrl	An addition interface to Desktop for implementation.

SessionCache	The cache for storing ZK sessions.
SessionCtrl	Additional interface of Session for implementation.
SessionResolver	Used with SessionsCtrl.setCurrent(SessionResolver) to resolve a session dynamically.
Storage	A storage interface is used for ZK web application to store application data with a string key and a data type value.
UiEngine	UI engine is responsible to process requests from the client, sends the response back to the client with the assistance of ExecutionCtrl.
UiFactory	Used to create Session, Desktop, Page, Component, Composer, and ServerPush.
Visualizer	A part of Execution for visualizing the components whose visual parts are modified.
WebAppCtrl	Additional interface of WebApp for implementation.
WebAppFactory	The factory used to instantiate the instance of WebApp.

Class Summary

Class	Description

Registry	A helper class for class registry for internal use only.
SessionsCtrl	An additional utilities for implementation related to Session.
ShadowElementsCtrl	Utilities for implementing components.
StringPropertyAccess	A String property class.
StubComponent	A stub component is a 'degenerated' component that does not maintain the states at the server.
StubsComponent	Represents a tree of StubComponent that are merged into a single component.
WebAppFactoryImpl	A web app factory implementation.
WebAppsCtrl	An additional utilities for implementation related to WebApp.
XmlContentRenderer	An implementation of ContentRenderer that renders the content as a Xml attribute (i.e., name="value").

Package org.zkoss.zk.ui.sys Description

Internal interfaces of user interfaces and factories (behind the scene). Most user interface, such as Component, has an internal interface, such as ComponentCtrl, used only by ZK internals. Application developers shall never use them.
