Constructor Detail

DefaultInjectionTarget

public DefaultInjectionTarget(EnhancedAnnotatedType<T> type,
                      Bean<T> bean,
                      BeanManagerImpl beanManager)

Method Detail

initInstantiator

protected Instantiator<T> initInstantiator(EnhancedAnnotatedType<T> type,
                               Bean<T> bean,
                               BeanManagerImpl beanManager,
                               Set<InjectionPoint> injectionPoints)

Description copied from class: AbstractInjectionTarget

Returns an instantiator that will be used to create a new instance of a given component. If the instantiator uses a constructor with injection points, the implementation of the AbstractInjectionTarget.initInstantiator(EnhancedAnnotatedType, Bean, BeanManagerImpl, Set) method is supposed to register all these injection points within the injectionPoints set passed in as a parameter.

Specified by:

initInstantiator in class AbstractInjectionTarget<T>

inject

public void inject(T instance,
          CreationalContext<T> ctx)

Description copied from interface: 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.

Parameters:

instance - The instance upon which to perform injection

ctx - The CreationalContext to use for creating new instances

postConstruct

public void postConstruct(T instance)

Description copied from interface: InjectionTarget

Calls the PostConstruct callback, if it exists, according to the semantics required by the Java EE platform specification.

Specified by:

postConstruct in interface InjectionTarget<T>

Overrides:

postConstruct in class AbstractInjectionTarget<T>

Parameters:

instance - The instance on which to invoke the PostConstruct method

preDestroy

public void preDestroy(T instance)

Description copied from interface: InjectionTarget

Calls the PreDestroy callback, if it exists, according to the semantics required by the Java EE platform specification.

Specified by:

preDestroy in interface InjectionTarget<T>

Overrides:

preDestroy in class AbstractInjectionTarget<T>

Parameters:

instance - The instance on which to invoke the PreDestroy method

dispose

public void dispose(T instance)

Description copied from interface: 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.

Specified by:

dispose in interface Producer<T>

Overrides:

dispose in class AbstractInjectionTarget<T>

Parameters:

instance - The instance to dispose

initializeAfterBeanDiscovery

public void initializeAfterBeanDiscovery(EnhancedAnnotatedType<T> annotatedType)

Overrides:

initializeAfterBeanDiscovery in class AbstractInjectionTarget<T>

getResourceInjectionPoints

public Set<ResourceInjectionPoint<?,?>> getResourceInjectionPoints()
