T
- The class of object produced by the producerpublic interface Producer<T>
Provides a generic operation for producing an instance of a type.
Method Summary | |
---|---|
void |
dispose(T instance)
Destroys the instance. |
java.util.Set<InjectionPoint> |
getInjectionPoints()
Returns the set of all InjectionPoints . |
T |
produce(CreationalContext<T> ctx)
Causes an instance to be produced via the Producer . |
Method Detail |
---|
T produce(CreationalContext<T> ctx)
Causes an instance to be produced via the Producer
.
If the Producer
represents a class, this will invoke the
constructor annotated Inject
if it exists, or the
constructor with no parameters otherwise. If the class has interceptors,
produce() is responsible for building the interceptors and
decorators of the instance.
If the Producer
represents a producer field or method, this will
invoke the producer method on, or access the producer field of, a
contextual instance of the bean that declares the producer.
ctx
- The CreationalContext
to
use for the produced object
void dispose(T instance)
Destroys the instance.
If the Producer
represents a class, then this operation does
nothing.
If the Producer
represents a producer field or method, this
calls the disposer method, if any, on a contextual instance of the
bean that declares the disposer method or performs any additional
required cleanup, if any, to destroy state associated with a resource.
instance
- The instance to disposejava.util.Set<InjectionPoint> getInjectionPoints()
Returns the set of all InjectionPoints
. If the
Producer
represents a class, then this returns returns the set of
InjectionPoint
objects representing all injected fields, bean
constructor parameters and initializer method parameters. For a producer
method, this returns the set of InjectionPoint
objects
representing all parameters of the producer method.
