T
- type of the instancepublic 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
Modifier and Type | Method and Description |

create(CreationalContext<T> creationalContext)
Create a new instance of the contextual type.

destroy(T instance,
CreationalContext<T> creationalContext)
Destroy an instance of the contextual type.

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
