Method Detail

getFlowScopeBeanHolder

protected FlowScopeBeanHolder getFlowScopeBeanHolder()

getFlowScopeBeanHolder

protected FlowScopeBeanHolder getFlowScopeBeanHolder(FacesContext facesContext)

getCurrentClientWindowFlowId

public String getCurrentClientWindowFlowId(FacesContext facesContext)

getContextualStorage

protected ContextualStorage getContextualStorage(boolean createIfNotExist,
                                     String clientWindowFlowId)

An implementation has to return the underlying storage which contains the items held in the Context.

Parameters:

createIfNotExist - whether a ContextualStorage shall get created if it doesn't yet exist.

Returns:

the underlying storage

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

isActive

public boolean isActive(FacesContext facesContext)

isPassivatingScope

public boolean isPassivatingScope()

Returns:

whether the served scope is a passivating scope

get

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

Specified by:

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

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

destroy

public boolean destroy(javax.enterprise.context.spi.Contextual bean)

Destroy the Contextual Instance of the given Bean.

Parameters:

bean - dictates which bean shall get cleaned up

Returns:

true if the bean was destroyed, false if there was no such bean.

destroyAllActive

public static void destroyAllActive(ContextualStorage storage)

Destroys all the Contextual Instances in the specified ContextualStorage. This is a static method to allow various holder objects to cleanup properly in @PreDestroy.

checkActive

protected void checkActive(FacesContext facesContext)

Make sure that the Context is really active.

Throws:

javax.enterprise.context.ContextNotActiveException - if there is no active Context for the current Thread.
