Solved Retrieving a serialized ItemStack from YAML

I'm wondering what is the appropriate way to do this. I'm serializing an ItemStack and storing it in YAML. I need to retrieve and deserialize it, but I can only receive in generics which I have trouble with casting. How can I accomplish this without suppressing warnings?

Below is the constructor where I should be deserializing. The passed in parameter is a direct read from YAML and the tradeItems are a class storage array.

Code:java

    protected Trade(List<Map<?, ?>> items) {
        int i = 0;
        for(Map<?, ?> m : items) {
            tradeItems[i] = ItemStack.deserialize((Map<String, Object>) m);
            i++;
        }
    }[/i]

 

What warnings?

 

Type safety unchecked cast warning on (Map<String, Object>) m

I'm not incredibly familiar with java generics and how to handle them appropriately. Is there another way to cast that?

 

Not sure if you've already eliminated this possiblity, or just weren't aware.. but ItemStack is ConfigurationSerializable. you can read and write ItemStacks to Config's natively. eg:

Code:java

 
// set it
getConfig().set("wool", new ItemStack(Material.WOOL));
// get it
ItemStack samewool = getConfig().getItemStack("wool");
 

 

No, I was not aware. That allows me to use my ItemStack contructor that I already have. Thank you very much.
