How to use getGE.buyItem with item ID (int) instead of item name (string)?

[Verify 0]

Hi guys,

I would like to know if there's a buyItem method that accepts item ID instead of item name. I assume that the item name is needed for the method to search for the item on the GE. If not, is there a Dreambot enum that contains Item names and their respective ID so I can have something like getItemName (ItemID) or will I have to access an external database to convert ID into name?

public String getItemName(int id) {
  Item item = new Item(id, 0, getClient().getInstance());
  return item != null ? item.getName() : null;
}
