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

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

Specified by:

Parameters:

bean - dictates which bean shall get cleaned up

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

destroyAllActive

public void destroyAllActive()

destroys all the Contextual Instances in the Storage returned by getContextualStorage(boolean).

destroyAllActive

public static void destroyAllActive(ContextualStorage storage)
