Use a Class for a generic type?
is there a way to for example do
In case this is xy problem: I have a class called DataObject for storing some extra data on things, and it has a generic type for what type of data it's storing. There's another class called DataMap that takes its own generic type and extends DataObject with a HashMap<DataObject<T>, DataObject<?>>. I'm then serializing it to json with gson as my method of storing it in a file, but I need a custom deserializer for it, and I'm getting errors for it not being able to convert HashMap<DataObject<?>, DataObject<?>> to HashMap<DataObject<T>, DataObject<T>>. Storing the class name in the json is my current idea for a workaround....
String clazz = "java.lang.String";
List<Class.forName(clazz)> list = new List<>();
String clazz = "java.lang.String";
List<Class.forName(clazz)> list = new List<>();

Recommendation to store permissions
Hi people i would like advices regarding what's the best way to store permissions without ending with a HUGE table in db and having java to properly handle them.
I was thinking on using a maybe numeric value, 1 read, 2 write, 4 delete where a value of 5 means it has delete and read value, a value of 6 read write and deleted and such.
But i really don't know if there is any other/recommended way.
