    • domainAndIDEquals

      public boolean domainAndIDEquals(ImmutableOutputInfo<MultiLabel> other)
      Description copied from interface: ImmutableOutputInfo
      Checks if the domain is the same as the other output info's domain, and that each element is mapped to the same id number.

      Parameters:
      other - The output info to compare.
      Returns:
