        Specified by:
        getScope in interface Context<PerLookup>
        Returns:
        may not return null, must return the scope for which this is a context

      • findOrCreate

        public <T> T findOrCreate​(ActiveDescriptor<T> activeDescriptor,
                          ServiceHandle<?> root)
        Description copied from interface: Context
        Creates a contextual instance of this ActiveDescriptor by calling its create method if there is no other matching contextual instance. If there is already a contextual instance it is returned. If parent is null then this must work like the find call
        Specified by:
        findOrCreate in interface Context<PerLookup>
        Parameters:
        activeDescriptor - The descriptor to use when creating instances
        root - The extended provider for the outermost parent being created
        Returns:
        A context instance. This value may NOT be null

        Parameters:
        descriptor - The descriptor to look for in this context
