getInjectionPoints

Set<InjectionPoint> getInjectionPoints()

Obtains the InjectionPoint objects representing injection points of the bean, that will be validated by the container at initialization time.

Returns:

the set of injection points of the bean

isNullable

boolean isNullable()

Determines if Contextual.create(CreationalContext) sometimes return a null value.

As of CDI 1.1 this method is deprecated and can safely always return false.
