      Parameters:
      optional - An optional value for remap
      Returns:

      public final ImmutableSingleBucketExchange withCommonExtension(Optional<? extends AdvancedExtension> optional)
      Copy the current immutable object by setting an optional value for the commonExtension attribute. A shallow reference equality check is used on unboxed optional value to prevent copying of the same value by returning this.
      Parameters:
      optional - An optional value for commonExtension
      Returns:
      A modified copy or this if not changed
