Examples of AlterableContext

javax.enterprise.context.spi.AlterableContext

Provides an operation for obtaining and destroying contextual instances with a particular scope of any contextual type. Any instance of {@code Context} is called a context object.

{@link AlterableContext} was introduced in CDI 1.1 to allow bean instances to be destroyed by the application. Extensions should implement {@link AlterableContext} instead of {@link Context}.

The context object is responsible for creating and destroying contextual instances by calling operations of {@link javax.enterprise.context.spi.Contextual}. In particular, the context object is responsible for destroying any contextual instance it creates by passing the instance to {@link javax.enterprise.context.spi.Contextual#destroy(Object,CreationalContext)} . A destroyed instance must notsubsequently be returned by {@code get()}. The context object must pass the same instance of {@link javax.enterprise.context.spi.CreationalContext} to {@code Contextual.destroy()} that it passed to{@code Contextual.create()} when it created the instance.

A custom context object may be registered with the container using {@link javax.enterprise.inject.spi.AfterBeanDiscovery#addContext(Context)}.
