  • Method Details

    • forSynthesis

      public static jakarta.enterprise.inject.Instance<Object> forSynthesis(CreationalContextImpl<?> creationalContext, boolean allowInjectionPointLookup)

    • iterator

      public Iterator<T> iterator()
      Description copied from interface: InjectableInstance
      This method attempts to resolve ambiguities.

      In general, if multiple beans are eligible then the container eliminates all beans that are:

      • not alternatives, except for producer methods and fields of beans that are alternatives,
      • default beans.
      Specified by:
      iterator in interface InjectableInstance<T>
      Specified by:
      iterator in interface Iterable<T>
      Returns:
      an iterator over the contextual references of the disambiguated beans
