Constructor Detail

AbstractMemberProducer

public AbstractMemberProducer(EnhancedAnnotatedMember<T,? super X,? extends Member> enhancedMember,
                      DisposalMethod<?,?> disposalMethod)

Method Detail

checkDeclaringBean

protected void checkDeclaringBean()

checkProducerReturnType

protected void checkProducerReturnType(EnhancedAnnotatedMember<T,? super X,? extends Member> enhancedMember)

Validates the producer method

producerCannotHaveWildcardBeanType

protected abstract DefinitionException producerCannotHaveWildcardBeanType(Object member)

producerWithTypeVariableBeanTypeMustBeDependent

protected abstract DefinitionException producerWithTypeVariableBeanTypeMustBeDependent(Object member)

getReceiver

protected Object getReceiver(CreationalContext<?> productCreationalContext,
                 CreationalContext<?> receiverCreationalContext)

Gets the receiver of the product. The two creational contexts need to be separated because the receiver only serves the product creation (it is not a dependent instance of the created instance).

Parameters:

productCreationalContext - the creational context of the produced instance

receiverCreationalContext - the creational context of the receiver

Returns:

The receiver

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.

Parameters:

instance - The instance to dispose

produce

public T produce(CreationalContext<T> ctx)

Description copied from interface: 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.

Parameters:

ctx - The CreationalContext to use for the produced object

Returns:

the instance produced

getDisposalMethod

public DisposalMethod<?,?> getDisposalMethod()

isTypeSerializable

protected boolean isTypeSerializable(Object object)

getBeanManager

public abstract BeanManagerImpl getBeanManager()

getDeclaringBean

public abstract Bean<X> getDeclaringBean()

getBean

public abstract 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>

getAnnotated

public abstract AnnotatedMember<? super X> getAnnotated()

Specified by:

getAnnotated in class AbstractProducer<T>

produce

protected abstract T produce(Object receiver,
        CreationalContext<T> ctx)

toString

public String toString()

Overrides:

toString in class Object
