package javax.enterprise.inject.spi;
/**
*
* Service interface implemented by extensions. An extension is a service provider declared in META-INF/services.
*
*
*
* Service providers may have {@linkplain javax.enterprise.event.Observes observer methods}, which may observe any event,
* including any {@linkplain javax.enterprise.inject.spi container lifecycle event}, and obtain an injected
* {@link javax.enterprise.inject.spi.BeanManager}.
*
*
*
* The container instantiates a single instance of each extension at the beginning of the application initialization process and
* maintains a reference to it until the application shuts down. The container delivers event notifications to this instance by
* calling its observer methods.
*
*
*
* Service providers are made available for injection as beans with the qualifier {@link javax.enterprise.inject.Default
* @Default}.
