## Set tipleri { #set-types }

Sonra bunu düşününce, tag’lerin tekrar etmemesi gerektiğini fark ederiz; büyük ihtimalle benzersiz string’ler olmalıdır.

Python’da benzersiz öğelerden oluşan kümeler için özel bir veri tipi vardır: `set`.

O zaman `tags`’i string’lerden oluşan bir set olarak tanımlayabiliriz:

      return null;
    }
    return set(rowIndex, columnIndex, null);
  }

  // TODO(jlevy): Add eraseRow and eraseColumn methods?

  @Override
  public int size() {
    return rowList.size() * columnList.size();
  }

  /**
   * Returns an unmodifiable set of all row key / column key / value triplets. Changes to the table
   * will update the returned set.
   *
