Producer
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 objectpublic void inject(T instance, CreationalContext<T> ctx)
InjectionTarget
Performs dependency injection upon the given object. Performs Java EE component environment injection, sets the value of all injected fields, and calls all initializer methods.

to use for creating new instancespublic void postConstruct(T instance)
InjectionTarget
Calls the PostConstruct
callback, if it exists, according to the semantics required by the Java
EE platform specification.

in interface InjectionTarget<T>
instance
- The instance on which to invoke the PostConstruct
methodpublic void preDestroy(T instance)
InjectionTarget
Calls the PreDestroy
callback, if it exists, according to the semantics required by the Java EE
platform specification.

instance
- The instance on which to invoke the PreDestroy
methodpublic void dispose(T instance)
Producer
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.
public Set<InjectionPoint> getInjectionPoints()
Producer
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.
