*
* An {@link ProducerFactory} can create an {@link Producer} for a given bean.
*
*
*
* The {@link ProducerFactory} obtained from {@link BeanManager#getProducerFactory(AnnotatedMethod, Bean)} or
* {@link BeanManager#getProducerFactory(AnnotatedField, Bean)} is capable of providing container created
* producers. This factory can be wrapped to add behavior to container created producers.
*
*
*
* For example:
*
*
*
* BeanAttributes<MyBean> myBeanAttributes = beanManager.createBeanAttributes(myBeanAnnotatedFieldField);
* beanManager.createBean(myBeanAttributes, MyBean.class, new ProducerFactory() {
*
* public <T> Producer<T> createProducer(Bean<T> bean) {
* return new WrappingProducer<T>(beanManager.getProducerFactory(myBeanAnnotatedField).createProducer(bean));
* }
* });
