  • Method Details

    • from

      public BUILDER from(AsyncConfig prototype)
      Update this builder from an existing prototype instance. This method disables automatic service discovery.
      Parameters:

      Returns:
      updated builder instance

    • from

      public BUILDER from(AsyncConfig.BuilderBase<?,?> builder)
      Update this builder from an existing prototype builder instance.
      Parameters:
      builder - existing builder prototype to update this builder from
      Returns:
      updated builder instance

    • config

      public BUILDER config(Config config)
      Update builder from configuration (node of this type). If a value is present in configuration, it would override currently configured values.
