Method Detail

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.

Specified by:

produce in interface Producer<T>

Parameters:

ctx - The CreationalContext to use for the produced object

Returns:

the instance produced

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.

Specified by:

inject in interface InjectionTarget<T>

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>

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>

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>

Parameters:

instance - The instance to dispose

getInjectionPoints

public Set<InjectionPoint> getInjectionPoints()

Description copied from interface: 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.

Specified by:

getInjectionPoints in interface Producer<T>

Returns:

the set of all injection points for the producer

getType

protected WeldClass<T> getType()

getBeanManager

protected BeanManagerImpl getBeanManager()

getInjectableFields

protected List<Set<FieldInjectionPoint<?,?>>> getInjectableFields()

getInitializerMethods

protected List<Set<MethodInjectionPoint<?,?>>> getInitializerMethods()
