JBoss Weld CDI for Java Platform

BeanManager

The core piece in extending CDI with extensions is the BeanManager, as it provides programmatic access to a CDI container via an API. BeanManager provides many useful operations for developers writing an extension, some of which include the ability to obtain beans, interceptors, decorators, observers, and contexts.

Accessing the BeanManager is not restricted to injection into extension observer methods; we are able to inject it into any bean or other Java EE component that supports injection.

@Inject
BeanManager beanManager;

Note

There is no restriction on when the BeanManager methods can be called during the life of an application.
