Owner of the producer field component

Constructor Detail

AbstractProducerBean

protected AbstractProducerBean(WebBeansType type,
                               Class<T> returnType,
                               InjectionTargetBean<?> ownerComponent)

Create a new instance.

Parameters:

type - webbeans typr

ownerComponent - owner bean

Method Detail

getParent

public InjectionTargetBean<?> getParent()

Specified by:

getParent in interface IBeanHasParent<T>

dispose

public void dispose(T instance,
                    javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

dispose in interface IBeanHasParent<T>

createInstance

protected T createInstance(javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Creates the instance of the bean that has a specific implementation type. Each subclass must define its own create mechanism.

Specified by:

createInstance in class AbstractOwbBean<T>

Parameters:

creationalContext - the contextual instance shall be created in

Returns:

instance of the bean

destroyBean

protected <K> void destroyBean(javax.enterprise.inject.spi.Bean<?> bean,
                               Object instance,
                               javax.enterprise.context.spi.CreationalContext<?> creationalContext)

Returns producer bean's owner bean instance.

Returns:

owner bean instance

getParentInstanceFromContext

protected Object getParentInstanceFromContext(javax.enterprise.context.spi.CreationalContext<?> creationalContext)

destroyInstance

protected void destroyInstance(T instance,
                               javax.enterprise.context.spi.CreationalContext<T> creationalContext)
