AbstractUiFactory

public AbstractUiFactory()

Method Details

start

public void start(WebApp wapp)

Description copied from interface: UiFactory

Starts this factory.

Specified by:

start in interface UiFactory

stop

public void stop(WebApp wapp)

Description copied from interface: UiFactory

Stops this factory.

Specified by:

stop in interface UiFactory

isRichlet

public boolean isRichlet(RequestInfo ri,
 boolean bRichlet)

Description copied from interface: UiFactory

Tests whether the specified request is a richlet.

If this method returns true, UiFactory.getRichlet(org.zkoss.zk.ui.sys.RequestInfo, java.lang.String) is called to create the richlet. Otherwise, UiFactory.getPageDefinition(org.zkoss.zk.ui.sys.RequestInfo, java.lang.String) is called to retrieve the page definition from a ZUML page.

Specified by:

isRichlet in interface UiFactory

bRichlet - the default value that this method shall return. It is a suggestion. If you don't know what to do, just return bRichlet.

Returns:

true if it is a richlet, or false if it is a ZUML page.

getRichlet

public Richlet getRichlet(RequestInfo ri,
 String path)

Description copied from interface: UiFactory

Returns a richlet for specified request, or null if the richlet is not found..

Specified by:

getRichlet in interface UiFactory

updateURI - the URI that is used as the base to generate URI for asynchronous updates. In other words, it is used to implement Desktop.getUpdateURI(java.lang.String)

path - the path to request this desktop, such as "/test/test.zul", or null if it is caused by a filter.

newDesktop

public Desktop newDesktop(RequestInfo ri,
 String updateURI,
