get

public <T> T get(javax.enterprise.context.spi.Contextual<T> component)

Specified by:

get in interface javax.enterprise.context.spi.Context

get

public <T> T get(javax.enterprise.context.spi.Contextual<T> component,
                 javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

get in interface javax.enterprise.context.spi.Context

getScope

public Class<? extends Annotation> getScope()

Specified by:

getScope in interface javax.enterprise.context.spi.Context

isActive

public boolean isActive()

Specified by:

isActive in interface javax.enterprise.context.spi.Context

isListenerForSource

public boolean isListenerForSource(Object source)

Specified by:

isListenerForSource in interface javax.faces.event.SystemEventListener

processEvent

public void processEvent(javax.faces.event.SystemEvent event)

We get PreDestroyViewMapEvent events from the JSF servlet and destroy our contextual instances. This should (theoretically!) also get fired if the webapp closes, so there should be no need to manually track all view scopes and destroy them at a shutdown.

Specified by:

processEvent in interface javax.faces.event.SystemEventListener

getViewRoot

protected javax.faces.component.UIViewRoot getViewRoot()

getViewMap
