Found some code for serialization of an ItemStack in Bukkit, how to deserialize it?

Question

I've dug up the following code for serializing an ItemStack in bukkit (Minecraft). I've been able to serialize an item in hand with the following:

itemString = ItemStackUtils.deserialize(player.getInventory().getItemInHand()); 

I can't figure out how to utilize the deserial call however. What I am trying to do is to pull an item from the players hand, serialize it, stick it into a config file, then when the player runs another command... deserialize it and slap it into their inventory. I am fairly certain this class will meet my needs if I just can get the last part working.

public final class ItemStackUtils {
    public static String getEnchants(ItemStack i){
        List<String> e = new ArrayList<String>();
        Map<Enchantment, Integer> en = i.getEnchantments();
        for(Enchantment t : en.keySet()) {
            e.add(t.getName() + ":" + en.get(t));
        }
        return StringUtils.join(e, ",");
    }
    public static String deserialize(ItemStack i){
        String[] parts = new String[6];
        parts[0] = i.getType().name();
        parts[1] = Integer.toString(i.getAmount());
        parts[2] = String.valueOf(i.getDurability());
        parts[3] = i.getItemMeta().getDisplayName();
        parts[4] = String.valueOf(i.getData().getData());
        parts[5] = getEnchants(i);
        return StringUtils.join(parts, ";");
    }
    public ItemStack deserial(String p){

        String[] a = p.split(";");
        ItemStack i = new ItemStack(Material.getMaterial(a[0]), Integer.parseInt(a[1]));
        i.setDurability((short) Integer.parseInt(a[2]));
        ItemMeta meta = i.getItemMeta();
        meta.setDisplayName(a[3]);
        i.setItemMeta(meta);
        MaterialData data = i.getData();
        data.setData((byte) Integer.parseInt(a[4]));
        i.setData(data);
        if (a.length > 5) {
            String[] parts = a[5].split(",");
            for (String s : parts) {
                String label = s.split(":")[0];
                String amplifier = s.split(":")[1];
                Enchantment type = Enchantment.getByName(label);
                if (type == null)
                    continue;
                int f;
                try {
                    f = Integer.parseInt(amplifier);
                } catch(Exception ex) {
                    continue;
                }
                i.addEnchantment(type, f);
            }
        }
        return i;
    }

}

ItemStack rItem = ItemStackUtils.deserial(itemString);
