Class PortletApplicationContext2

java.lang.Object
  com.vaadin.terminal.gwt.server.AbstractWebApplicationContext
      com.vaadin.terminal.gwt.server.PortletApplicationContext2

All Implemented Interfaces:

ApplicationContext, Serializable, EventListener, HttpSessionBindingListener

public class PortletApplicationContext2
extends AbstractWebApplicationContext

TODO Write documentation, fix JavaDoc tags. This is automatically registered as a HttpSessionBindingListener when PortletSession#setAttribute() is called with the context as value.

public PortletApplicationContext2()

Method Detail

getBaseDirectory

public File getBaseDirectory()

Description copied from interface: ApplicationContext

Returns application context base directory. Typically an application is deployed in a such way that is has an application directory. For web applications this directory is the root directory of the web applications. In some cases applications might not have an application directory (for example web applications running inside a war).

Returns:

The application base directory or null if the application has no base directory.

public String generateApplicationResourceURL(ApplicationResource resource,
                                             String mapKey)

Description copied from interface: ApplicationContext

Generate a URL that can be used as the relative location of e.g. an ApplicationResource. This method should only be called from the processing of a UIDL request, not from a background thread. The return value is null if used outside a suitable request.

Specified by:

generateApplicationResourceURL in interface ApplicationContext

Overrides:

generateApplicationResourceURL in class AbstractWebApplicationContext

mapKey - a key for the resource that can later be extracted from a URL with ApplicationContext.getURLKey(URL, String)

generateActionURL

public javax.portlet.PortletURL generateActionURL(String action)

Creates a new action URL.

Parameters:

action -

Returns:

action URL or null if called outside a MimeRequest (outside a UIDL request or similar)

sendPortletEvent

public void sendPortletEvent(Window window,
                             QName name,
                             Serializable value)
                      throws IllegalStateException

Sends a portlet event to the indicated destination. Internally, an action may be created and opened, as an event cannot be sent directly from all types of requests. The event destinations and values need to be kept in the context until sent. Any memory leaks if the action fails are limited to the session. Event names for events sent and received by a portlet need to be declared in portlet.xml .

Parameters:

window - a window in which a temporary action URL can be opened if necessary

name - event name

value - event value object that is Serializable and, if appropriate, has a valid JAXB annotation

Throws:

IllegalStateException

setSharedRenderParameter

public void setSharedRenderParameter(Window window,
                                     String name,
                                     String value)
                              throws IllegalStateException

Sets a shared portlet parameter. Internally, an action may be created and opened, as shared parameters cannot be set directly from all types of requests. The parameters and values need to be kept in the context until sent. Any memory leaks if the action fails are limited to the session. Shared parameters set or read by a portlet need to be declared in portlet.xml .

Parameters:

window - a window in which a temporary action URL can be opened if necessary

name - parameter identifier

value - parameter value

Throws:

IllegalStateException

setPortletMode

public void setPortletMode(Window window,
                           javax.portlet.PortletMode portletMode)
                    throws IllegalStateException,
                           javax.portlet.PortletModeException

Sets the portlet mode. This may trigger a new render request. Portlet modes used by a portlet need to be declared in portlet.xml .

Parameters:

window - a window in which the render URL can be opened if necessary

portletMode - the portlet mode to switch to

Throws:

javax.portlet.PortletModeException - if the portlet mode is not allowed for some reason (configuration, permissions etc.)

IllegalStateException

isProductionMode

public boolean isProductionMode()

setProductionMode

public void setProductionMode(boolean productionMode)
