public interface Contextual<T>
Defines operations to create and destroy contextual instances of a
certain type. Any implementation of Contextual
is called a
contextual type. In particular, all beans are contextual types.
Bean
Method Summary | |
---|---|
T |
create(CreationalContext<T> creationalContext)
Create a new instance of the contextual type. |
void |
destroy(T instance,
CreationalContext<T> creationalContext)
Destroy an instance of the contextual type. |
Method Detail |

T create(CreationalContext<T> creationalContext)
CreationalContext
when obtaining contextual references to inject, in order to ensure
that any dependent objects are associated with the contextual instance
that is being created. An implementation may call
CreationalContext.push(Object)
between instantiation and injection to help the container minimize the
use of client proxy objects.
creationalContext
- the context in which this instance is being created
CreationException
- if a checked exception occurs while creating the instancevoid destroy(T instance, CreationalContext<T> creationalContext)
CreationalContext.release()
to allow the container to destroy dependent objects of the contextual
instance.
instance
- the contextual instance to destroycreationalContext
- the context in which this instance was created
