org.jboss.weld.injection.producer.BasicInjectionTarget<T>

All Implemented Interfaces:

javax.enterprise.inject.spi.InjectionTarget<T>, javax.enterprise.inject.spi.Producer<T>, org.jboss.weld.manager.api.WeldInjectionTarget<T>

Direct Known Subclasses:

BeanInjectionTarget, NonProducibleInjectionTarget

public class BasicInjectionTarget<T>
extends AbstractProducer<T>
implements org.jboss.weld.manager.api.WeldInjectionTarget<T>

Method Detail

create

public static <T> BasicInjectionTarget<T> create(EnhancedAnnotatedType<T> type,
                                                 javax.enterprise.inject.spi.Bean<T> bean,

public static <T> BasicInjectionTarget<T> createDefault(EnhancedAnnotatedType<T> type,
                                                        javax.enterprise.inject.spi.Bean<T> bean,
                                                        BeanManagerImpl beanManager,

createNonCdiInterceptor

public static <T> BasicInjectionTarget<T> createNonCdiInterceptor(EnhancedAnnotatedType<T> type,
                                                                  BeanManagerImpl beanManager)

Creates InjectionTarget for interceptors which do not have associated Interceptor. These interceptors are a result of using Interceptors annotation directly on the target class.

checkType

protected void checkType(EnhancedAnnotatedType<T> type)

produce

public T produce(javax.enterprise.context.spi.CreationalContext<T> ctx)

Specified by:

produce in interface javax.enterprise.inject.spi.Producer<T>

inject

public void inject(T instance,
                   javax.enterprise.context.spi.CreationalContext<T> ctx)

Specified by:

inject in interface javax.enterprise.inject.spi.InjectionTarget<T>

postConstruct

public void postConstruct(T instance)

Specified by:

postConstruct in interface javax.enterprise.inject.spi.InjectionTarget<T>

preDestroy

public void preDestroy(T instance)

Specified by:

preDestroy in interface javax.enterprise.inject.spi.InjectionTarget<T>

dispose

public void dispose(T instance)

Specified by:

dispose in interface javax.enterprise.inject.spi.Producer<T>

getInjectionPoints

public Set<javax.enterprise.inject.spi.InjectionPoint> getInjectionPoints()

Specified by:

getInjectionPoints in interface javax.enterprise.inject.spi.Producer<T>

getType

protected SlimAnnotatedType<T> getType()

getBeanManager

public BeanManagerImpl getBeanManager()

getInstantiator

public Instantiator<T> getInstantiator()

setInstantiator

public void setInstantiator(Instantiator<T> instantiator)

hasInterceptors

public boolean hasInterceptors()

hasDecorators

public boolean hasDecorators()

initializeAfterBeanDiscovery

protected void initializeAfterBeanDiscovery(EnhancedAnnotatedType<T> annotatedType)

initInstantiator

protected Instantiator<T> initInstantiator(EnhancedAnnotatedType<T> type,
                                           javax.enterprise.inject.spi.Bean<T> bean,
                                           BeanManagerImpl beanManager,
                                           Set<javax.enterprise.inject.spi.InjectionPoint> injectionPoints)

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 initInstantiator(EnhancedAnnotatedType, Bean, BeanManagerImpl, Set) method is supposed to register all these injection points within the injectionPoints set passed in as a parameter.

getAnnotated

public javax.enterprise.inject.spi.AnnotatedType<T> getAnnotated()

Specified by:

getAnnotated in class AbstractProducer<T>

getAnnotatedType

public javax.enterprise.inject.spi.AnnotatedType<T> getAnnotatedType()

Specified by:

getAnnotatedType in interface org.jboss.weld.manager.api.WeldInjectionTarget<T>

getInjector

public Injector<T> getInjector()

getLifecycleCallbackInvoker

public LifecycleCallbackInvoker<T> getLifecycleCallbackInvoker()

toString

public String toString()

Overrides:

toString in class Object

getBean

public javax.enterprise.inject.spi.Bean<T> getBean()

Description copied from class: AbstractProducer

Returns a Bean this producer is associated with or null if no such bean exists.

Specified by:

getBean in class AbstractProducer<T>
