Constructor Details

ContextualStorage

public ContextualStorage(jakarta.enterprise.inject.spi.BeanManager beanManager,
 boolean concurrent,
 boolean passivationCapable)

Parameters:

beanManager - is needed for serialisation

concurrent - whether the ContextualStorage might get accessed concurrently by different threads

passivationCapable - whether the storage is for passivation capable Scopes

Method Details

getStorage

public Map<Object,ContextualInstanceInfo<?>> getStorage()

Returns:

the underlying storage map.

isConcurrent

public boolean isConcurrent()

Returns:

whether the ContextualStorage might get accessed concurrently by different threads.

createContextualInstance

public <T> T createContextualInstance(jakarta.enterprise.context.spi.Contextual<T> bean,
 jakarta.enterprise.context.spi.CreationalContext<T> creationalContext)

Type Parameters:

T -

Parameters:

bean -

creationalContext -

Returns:

getBeanKey

public <T> Object getBeanKey(jakarta.enterprise.context.spi.Contextual<T> bean)

If the context is a passivating scope then we return the passivationId of the Bean. Otherwise we use the Bean directly.

Returns:

the key to use in the context map

getBean

public jakarta.enterprise.context.spi.Contextual<?> getBean(Object beanKey)

Restores the Bean from its beanKey.
