      Description copied from interface: ComponentMonitor
      No Component has been found for the key in question. Implementers of this have a last chance opportunity to specify something for the need. This is only relevant to component dependencies, and not to container.getComponent() in your user code.

      Specified by:
      newInjector in interface ComponentMonitor
      Parameters:
      injector -
      Returns:
      an Injector. For most implementations, the same one as was passed in.
