org.apache.myfaces.cdi.util.ContextualStorage

All Implemented Interfaces:

Serializable

public class ContextualStorage
extends Object
implements Serializable

Constructor Detail

ContextualStorage

public ContextualStorage()

ContextualStorage

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

Parameters:

beanManager - is needed for serialisation

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

passivating - whether the served scope is a passivating scope

Method Detail

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, this is mainly for Quarkus.

Parameters:

bean -

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. It returns null if the beanKey does not belong to a bean or is not Contextual.

isActivated

public boolean isActivated()

activate

public void activate()

deactivate

public void deactivate()
