Method Detail

getContextualStorage

protected org.apache.deltaspike.core.util.context.ContextualStorage getContextualStorage(boolean createIfNotExists)

Specified by:

getContextualStorage in class org.apache.deltaspike.core.util.context.AbstractContext

get

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

Specified by:

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

Overrides:

get in class org.apache.deltaspike.core.util.context.AbstractContext

get

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

Specified by:

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

Overrides:

get in class org.apache.deltaspike.core.util.context.AbstractContext

getScope

public Class<? extends Annotation> getScope()

Specified by:

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

isActive

public boolean isActive()

The view context is active if a valid ViewRoot could be detected.

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

SystemEventListener.processEvent(javax.faces.event.SystemEvent)

getViewRoot

protected javax.faces.component.UIViewRoot getViewRoot()

getViewMap

protected Map<String,Object> getViewMap()
