- * MetaItem is item that can have up to Short.MAX_VALUE items inside one id.

- * They can also have different burn time, plus be handheld, oredicted or invisible!
- * They also can be reactor components.

  * <p>
  * You can also extend this class and occupy some of it's MetaData, and just pass an meta offset in constructor, and
  * everything will work properly.
  * <p>
  * Items are added in MetaItem via {@link #addItem(int, String)}. You will get {@link MetaValueItem} instance, which you
  * can configure in builder-alike pattern:
- * {@code addItem(0, "test_item").addStats(new ElectricStats(10000, 1,  false)) }
- * This will add single-use (not rechargeable) LV battery with initial capacity 10000 EU
