}
this is a very chatgpt-d solution and i get what its doing, altho i was hoping to avoid having to use a Class<T> clazz param for clarity reasons. if that's not possible or this is the best solution i can live with it tho... because the syntax would go from LootTable lt1 = new LootTable( "loot1", "{...json...}"); to LootTable lt1 = JsonFileFactory.fromNameAndContent(LootTable.class, "loot1", "{...json...}");
