ContextualStorage (Apache MyFaces Core 4.0 - Impl 4.0.0-RC3 API)

java.lang.Object
- org.apache.myfaces.cdi.util.ContextualStorage

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

ViewScopeContextualStorage
```
public class ContextualStorage
extends Object
implements Serializable
```
This Storage holds all information needed for storing Contextual Instances in a Context. It also addresses Serialisation in case of passivating scopes.

Constructor Detail
- ContextualStorage
```
public ContextualStorage()
```
- ContextualStorage
```
public ContextualStorage(jakarta.enterprise.inject.spi.BeanManager beanManager,
                         boolean concurrent)
```
  Parameters:
  
  beanManager - is needed for serialisation
  
  concurrent - whether the ContextualStorage might get accessed concurrently by different threads

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.
  
  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.
