Why LWJGL uses arrays for pointers instead of AtomicIntegers?

[CiroZDP]

Question

Java provides us with several classes for this purpose: AtomicInteger and AtomicLong (there are more). These classes hold a value which is usually a number or a decimal number. The values ​​contained in these classes can be changed at any time and can be used as an argument in a method.

For example, there are functions in glfw that allow you to get the mouse position, these functions use an array of doubles to represent a pointer, but, in my humble opinion, I think it would be a good idea to replace these arrays with something that "makes more sense".

Some ideas:

Thanks in advance.

EDIT: There are no atomical classes for decimal numbers, but you can use AtomicReference<Double> dptr = new AtomicReference<>(); for creating a atomical reference to any double number.

Atomic integers (and other atomic types) are meant for synchronization between threads, and are probably much more expensive than simple arrays. Besides, they can only store 1 value, whereas some LWJGL function require longer arrays.
