Examples of javax.enterprise.context.spi.CreationalContext

javax.enterprise.context.spi.CreationalContext
The CreationalContext holds incomplete Bean instances. This may be caused by a situation like in the following example: @ApplicationScoped class Foo { @Current Bar _bar; } @ApplicationScoped class Bar { @Current Foo _bar; }
Generally it is used for prohibiting the circular references of the webbeans.
